Answer:
x=3
Step-by-step explanation:
We can use the slope formula to help complete this question
m = (y2-y1)/(x2-x1)
-1 = ( -6-0)/(x- -3)
-1 = -6/ (x+3)
Multiply each side by (x+3)
-x-3 = -6
Add 3 to each side
-x -3+3 = -6+3
-x =-3
Multiply each side by -1
x = 3
Answer:
Step-by-step explanation:
line perpendicular to ax+by=c is
bx-ay=k, where k is a constant.
if it passes through (-1,2) then
b(-1)-a(2)=k
or k=b-2a
so reqd. eq . is bx-ay=b-2a
