Answer:

A: y = -0.4x -5

B: y = -1x +7

C: y = 1.25x +7

D: y = 3x -5

Explanation:

See the attached worksheet. Finding the equations for the graph lines is reasonabvly straightforward, but the number of lines quadruples the space required. We'll find equations of the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0). The worksheet notes the 4 steps needed:

1. mark any two points on the graph for each line.

2. Find the slope for each line by calculating the Rise/Run

3. Find the y-intercepts from the graph.

4. Assemoble the slopes and intercepts into the four equations.

Use a spreasheet to keep organized, and nbe patient. Check the equations using a free online graphing utility (e.g., DESMOS).
