Answer:
y = -4x - 2
Explanation:
Look at point (0, -2).
When x = 0, y = -2. The y-intercept = b = -2.
y = mx + b
y = mx - 2
Now we use two points to find the slop, m.
Use points (0, -2) and (-2, 6)
m = (y_2 - y_1)/(x_2 - x_1)
m = (6 - (-2))/(-2 - 0)
m = 8/(-2)
m = -4
The slope is -4.
The equation is
y = -4x - 2
