Answer:
y = x +
Step-by-step explanation:
Calculate the slope of line m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 2) and (x₂, y₂ ) = (0, - 3) ← 2 points on the line
m = =
= -
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, then
y = x + c ← is the partial equation in slope- intercept form
To find c substitute (3, 2 ) into the partial equation
2 = + c ⇒ c = 2 -
=
y = x +
← equation of perpendicular line
