The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have y-intercept b = 1. Therefore y = mx + 1.

The graph passing through the point (-2, 2). Substitute the coordinates to the equation:

2 = m(-2) + 1 subtract 1 from both sides

1 = -2m divide both sides by -2

m = -1/2

Answer: B. y = -1/2 x + 1
