Question

Find the equation of a line that is perpendicular...

Answer 1

wait i made a mistake; i'll fix it

Answer 2

ok

Answer 3

you know that y=mx+b gives you the slope as m; in your case m=-1/2. the line that is perpendicular has a slope that is the negative reciprocal of -1/2 or m=2. using the perpendicular slope and the given point (-2,2) we use the point-slope formula
y−2=2(x+2)
and solve for y
y=2x+4+2
y=2x+6
this is the perpendicular line to

Answer 4

Ok i got it

Answer 5

here is what is going on geometrically; the blue line is the line we found :})
