    Answer:

    -4

    Step-by-step 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.
