Answer:

see explanation

Step-by-step explanation:

y = ax + b is the equation in slope- intercept form

where a is the slope of the line and b is the y- intercept

To find a use the slope formula

a = (y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (1, - 2)

a = \frac{-2-1}{1+3} = - \frac{3}{4} = - 0.75, hence

y = - 0.75 + b

To find b substitute either of the 2 points into the equation

using (1, - 2), then

- 2 = - 0.75 + b ⇒ b = - 2 + 0.75 = - 1.25 = - 1 \frac{1}{4}
