Where my math genius at? lets eachother

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 = - 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

= - = - = , thus

y = x + c ← is the partial equation of the line

To find c substitute (8, 1) into the partial equation

1 = 2 + c ⇒ c = 1 - 2 = - 1

y = x - 1 ← equation of line

i believe it's a.

i'm not sure on this one, most likely correct.
