Answer:

y = -3x - 1

Explanation:

First, we find the y-intercept using y=mx+b

y = mx+b [insert x and y, and the slope(m)]

-7 = (-3)(2) + b

-7 = -6 + b [use inverse operations to bring over the -6]

-1 = b

The slope is given to us. (-3)

With all the information, you can get the equation.

m = -3

b = -1

y = mx+b

y = -3x - 1
