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

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.
