Write the equation of the line with slope 4 through the point (-2, 5).

• y = 4x - 13

• y = 4x + 13

• y = 4x - 3

• y = 4x + 3

Write the equation of the line with slope 5/2 through the point (8, -2).

• y = 5/2x + 18

• y = 5/2x - 18

• y = 5/2x + 22

• y = 5/2x - 22

Which is an equation for the line that contains (1, 2) and has a slope of 4?

• y = 2x - 4

• y = -2x + 4

• y = 4x - 2

• y = -4x + 2

What is the rate of change (slope) of the line shown?

• 40/1

• 50/1

• 10/1

• 1/10

How can you find the rate of change from a non-proportional graph?

• I can pick a point, then divide y/x.

• I can look at the point where the line crosses the vertical axis.

• I can take any two points on the graph and divide the amount of vertical change (y-y) by the amount of horizontal change (x-x).

• I can use any one point to fin the rate of change.

• I can count rise over run.
