Use the given conditions to write an equation for the line i

Use the given conditions to write an equation for the line in point-slope form and general form.

Passing through (6,-9)

and perpendicular to the line whose equation is x-4y-3=0

x- 4y -3 =0

Rearraning : y = x/4 - 3/4

slope = 1/4

A line perpendicular to (m = 1/4) would have m = -4

So, y = -4x +c; Given ( 6, -9) Find c

-9 = -24 +c ----> c= 15

So, y = -4x +15
