Answer:

y = -4x - 13

Step-by-step explanation:

Use point - slope form to convert to y = mx + b form

1. Find the slope using y2 - y1 / x2 - x1

    3 + 5 / -4 + 2

    m = -4

2. Plug into point - slope form: y - y1 = m (x - x1)

    y + 5 = -4 (x + 2)

    Distribute

    y + 5 = -4x - 8

    Subtract 5 from both sides

    y = -4x - 13
