    Answer:

    y = 8/5x – 3

    Step-by-step explanation:

    First, find the slope using rise over run (y2 – y1) / (x2 – x1)

    (y2 – y1) / (x2 – x1)

    (-19 – 5) / (-10 – 5)

    -24 / -15

    = 8/5

    Plug in the slope and a given point into y = mx + b, and solve for b

    y = mx + b

    5 = 8/5(5) + b

    5 = 8 + b

    -3 = b

    Plug in the slope and b into y = mx + b

    y = 8/5x – 3

    So, the equation is y = 8/5x – 3
