    Answer:

    y = -4x + 2

    Step-by-step explanation:

    To figure out the slope, plug the coordinates in the formula.

    y2 – y1 / x2 – x1

    = 6 – (-6) / -1 -2

    = -4

    Now you need to find the y-intercept, take the coordinates and plug them into your equation so far, which is y = -4x + b

    y = -4x + b

    -6 = -4(2) +b

    -6 = -8 + b

    2 = b
