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 )

Rearrange 5x - y = - 4 into this form

Subtract 5x from both sides

- y = - 5x - 4 ( multiply through by - 1 )

y = 5x + 4 ← in slope- intercept form

with slope m = 5

Given a line with slope m then the slope of a line perpendicular to it is

= - = - , thus

y = - x + c ← is the partial equation

To fond c substitute (- 3, 2) into the partial equation

2 = + c ⇒ c = 2 - =

y = - x + ← in slope- intercept form
