Question

write an equation in slope intercept form of the line passing through the given points and is perpendicular to the graph of the given equations
1) (2,-2) ; y=-x-2
2)(2,-1) ; y=-3/2x+6
3)(4,2) ; y=-3
4)(-2,3) ; y-1/2x1

Answer 1

if the given line has slope m, then your perpendicular line must have slope -1/m. Then use the point-slope form of the line you want.

So, for the first one, you need a line through (2,-2) with slope 1:
y+2 = 1(x-2)

Do the others in like wise...
