Answer:
m = - 1 and b = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line
m =
=
=
= - 1
b is the y- intercept, that is where the graph crosses the y- axis.
line crosses the y- axis at (0, - 1 ) ⇒ b = - 1
