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
