Question

If a line with the slope of -1 goes through the point (-2,-2), then solve for b: y=mx+b

Answer 1

b = -4.

Explanation:

In this case, y = -2, m = -1, and x = -2.

-2 = (-1) * (-2) + b

-2 = 2 + b

b + 2 = -2

b = -4

Hope this helps!

Answer 2

b = -4

Explanation:

Well we already have m which is slope which is -1.

And if we start at (-2,-2) and go down using the slope we get -4 as the y intercept or b.

Thus,

-4 is the y intercept or b.

Hope this helps :)
