Mandy used the graph to write the equation of the line it represents. She took these steps.

1. y−intercept = (0, 2)

2. Slope =
rise
run
=
− 2
4
= −
1
2

3. Substituting values into y = mx + b

y = x +
On a coordinate plane, a line goes through points (0, 2) and (4, 0). The run = 4 and the rise = negative 2.
