Question

A line passing through (1,-4) and (-2,5)

Answer 1

y = -3x - 1.

Explanation:

First find the slope by doing 5 - (-4) over -2 -1. You can simplify this to 5 + 4 over -2 - 1. You'll get 9/-3 = -3. Then use slope intercept form to find the y - intercept, if there is any, y = mx + b. Substitute your values. Y = 5, X = -2, and M = -3. You're equation should be 5 = -2(-3) + b. -2 x -3 = 6. 5 - 6 = -1. You're final equation should be y = -3x - 1.
