Geometry question slope intercept form
2 answers:
Okay so a perpendicular line has a slope of the opposite reciprocal so for example in this equation the slope is 2 so the slope of a perpendicular equation would be -1/2 now since you know that you can put that in the slope intercept equation
Now you have y=-1/2x+b and since you have a point (point A) you can plug it in and solve for b
-8=-1/2(4)+b
-8=-2+b
b=-6
Now you have both parts simply put it in and you have the equation
y=-1/2x-6
I also attached the image with both to prove they are perpendicular
