## Explain constant rate of change

Rate of Change A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then rate of change = change in y change in x

is a linear function, which is defined as a function with a constant rate of change, following word sentence may be used to describe the function relationship. Converting rates of change is fairly straight forward so long as you remember a linear model is used to describe data, it is assuming a constant rate of change. Find out how to solve real life problems that involve slope and rate of change. Explain what you think may have happened during interval C. 3. If the rate of change for interval A had remained constant throughout the whole marathon, how  It is also commonly abbreviated as ms−2. For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2  And the drying rate always is changing in this constant rate period.) In this case , the drying rate per unit mass of dry matter Φ, as defined in Section 22.3.1  a is the constant term or the y intercept. It is the value of the It is also known as the slope and gives the rate of change of the dependent variable. Graphing a linear function What is total cost at varying levels of output? let x = units of output

## Students calculate the rate of change also know as the constant of and y represents the dependent variable, independent variables describe the input values

2. Explain what you think may have happened during interval C. During interval C, Karen took a break and stopped running. During that 1/2 hour time period, her distance did not increase. 3. If the rate of change for interval A had remained constant throughout the whole marathon, how long would it have taken Karen to finish the marathon? Rate of Change Positive rate of change. When the value of increases, the value of increases and the graph slants upward. Negative rate of change. When the value of increases, the value of decreases and the graph slants downward. Zero rate of change. When the value of increases, the value of The average rate of change is finding the rate something changes over a period of time. We can look at average rate of change as finding the slope of a series of points. The slope is found by finding the difference in one variable divided by the difference in another variable. Rate of Change. In the examples above the slope of line corresponds to the rate of change. e.g. in an x-y graph, a slope of 2 means that y increases by 2 for every increase of 1 in x. The examples below show how the slope shows the rate of change using real-life examples in place of just numbers.

### is a linear function, which is defined as a function with a constant rate of change, following word sentence may be used to describe the function relationship.

In this lesson you will learn calculate the rate of change of a linear function by examining the four representations of a function. What is a Rate of Change? Get up and walk across the room. Did your position change? Of course it did! You are on the other side of the room now. How quickly   Zero rate of change. When the value of x increases, the value of y remains constant. That is, there is no change in y value and the graph is a horizontal line . Since a is a constant, the derivative f'(r) is 2ar, and ing that the velocily is increasing at a constant rate. Note hour in 1984, what is the rate of change of price. The average rate of change of any function is a concept that is not new to you. You have studied For a line, it was unique in the fact that the slope was constant. It didn't To find the slope, the definition is the change in y over the change of x. Explain your reasoning. Describe a road with a 0% grade. Page 21. TIPS4RM: Grade 9 Applied –

### A constant rate of change is predictable - you can almost assume the same rate of change forever. A variable rate of change is affected by other forces or events and therefore is not easily predictable.

Rate of Change and Slope . Learning Objective(s) This ratio is constant between any two points along a straight line, which means that the slope of a straight line is constant, too, no matter where it is measured along the line. Slope Formula and Coordinates .

## Explain what the constant rate of change means in this context Stephen earns extra money babysitting he charges \$31.25 for 5 hours and \$50 for 8 hours Follow • 2

Students calculate the rate of change also know as the constant of and y represents the dependent variable, independent variables describe the input values  Rate of change is used to mean constant rate of change in the subsequent lessons. Students also explain whether the rate of change of a linear function is  Definition: Time series & the values of a variable recorded at different points in time Example: US GDP per capita grows at constant rate of 2% per year.

Explain the meaning of the rate of change. 62/87,21 To find the rate of change, use the coordinates (2004, 5545) and (2008, 6830). So, the rate of change is 321.25. This rate of change means there was an average increase of 321.25 women per year competing in triathlons.
