Interpreting Slope and Y-Intercept of Equations

Identify the slope and y-intercept of the equation y = 4x - 7.

• Slope = 7, Y-intercept = -4

• Slope = 4, Y-intercept = -7

• Slope = 4, Y-intercept = 7

• Slope = -7, Y-intercept = 4

Identify the slope and y-intercept of the equation y = -5x + 3.

• Slope = 5, Y-intercept = -3

• Slope = 0, Y-intercept = 5

• Slope = 3, Y-intercept = -5

• Slope = -5, Y-intercept = 3

Select the statement that is true.

• The slope represent the number of cookies in a package.

• The slope represents the total number of calories consumed.

• The slope represents the total number of cookies eaten.

• The slope of the scenario means calories consumed per cookies eaten

Compare the initial values and the rates of change.

• The functions have different initial values and different rates of change.

• The rates of change are the same, but the initial values are different.

• The functions have the same initial value, but the rates of change differ.

• The y-intercepts are the same, but the rates of change differ.
