Finding Slopes in Graphs

Write the equation that represents the line. Put the equation in slope intercept form and solve for b (y-intercept).

• Cannot be determined.

• b = 4

Non-vertical line has:

• Only one slope

• Two slopes

• Zero slopes

• Many slopes

In the slope form intercept: y = mx + b, the b is the?

• slope

• y-intercept

• x coordinate

• y coodrinate

The table represents some points on the graph of a linear function. What is the rate of change of y with respect to x for this function?

• 70

• 7.5

• -0.5

• -2.5

• YES

• NO

Based off the information in the graph, what is the rate of change?

• -10 ft per second

• 15 ft per second

• 10 ft per second 

• -15 ft per second

Remember, when finding rate of change (slope), pay attention to the DIRECTION of the values. There is a big difference between a positive and negative slope! Select YES to continue.

• YES

• NO

Which equation represents the line shown on the graph?

Which of the following equations match the given graph?

• y > 2x - 5

• y ≥ 7/4x + 2

• x < -5

• x > -5

Who has the greater rate of change?

• CJ has a greater rate of change with 13/2

• Holland has a greater rate of change with 6

• CJ has a greater rate of change with 2/13

• They have the same rate of change.
