Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x +
← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= -
Using the point- slope form
with m = - and (x₁, y₁ ) = (- 2, 4) , then
y - 4 = - (x - (- 2) ) , that is
y - 4 = - (x + 2) ← distribute
y - 4 = - x - 3 ( add 4 to both sides )
y = - x + 1 ← in slope- intercept form
