Question

Find an equation, in slope-intercept form, that passes through point (-5, 6) with slope -2.

Select one:
a. y = -2x + 3
b. y = -2x - 4
c. y = 2x - 4
d. y = 2x + 3

Answer 1

The desired equation is y = -2x - 4

Explanation:

The general slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Starting from that, substitute the given values for m, x and y and calculate b:

6 = -2(-5) + b. Then 6 = 10 + b, and b = -4.

The desired equation is y = -2x - 4.
