Answer:

y = -4/5x - 0.8

Explanation:

A(-6, 4)

B(4, -4)

Find slope using the two points above:

m = (y₂ - y₁) / (x₂ - x₁)

= (-4 - 4) / (4 - (-6))

= -8 / 10

m = -4/5

Find y-intercept using m from above and anyone point, let's use (-6, 4):

y = mx + b

4 = -4/5(-6) + b

4 = 24/5 + b

b = -0.8

Use m and b from above to form equation of line:

y = mx + b

y = -4/5x - 0.8
