CAN YOU PLEASE PLEASE HELP ME PLEASE

y = - x + 9

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 = 4x - 3 ← is in slope- intercept form

with slope m = 4

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

= - = - , then

y = - x + c ← is the partial equation

To find c substitute (4, 8) into the partial equation

8 = - 1 + c ⇒ c = 8 + 1 = 9

y = - x + 9 ← equation of perpendicular line
