Answer:

-4

Explanation:


\text {Using slope intercept form and the information provided: }y = 3x + b\\x = -1\\y = - 7\\\\\text{So: }


y = 3x + b \rightarrow -7 = 3(-1) +b

Solve for B.


-7 = 3(-1)+b\\3 * -1 = -3\\-7 = -3 + b


\text {Add 3 to both sides: } -7 +3 = -3(+3) +b\\\\-4 = b

Your y-intercept should be -4.
