Question

Choose the equation of the line passing through the point (-4, -2) and perpendicular to y = -x + 6

Answer 1

Ed:
This is a great opportunity to apply the "point-slope formula for the equation of a straight line":\[y-y _{?}=m(x-x _{0)}\]

Answer 2

as you are given a point on the line whose equation you want to find.

But where does the necessary slope, m, come from?

You're given the line y = -x + 6. But the slope of the desired line is not -1. What is it, and how do you obtain that slope?

Answer 3

quick question what do i do with the -x

Answer 4

choose or find?
for perpendicular gradient, always use this formula:



y=mx+c
y=1x+c
substitute in the point as it is shared with both lines
-2=1(-4)+c
c=?

then find your equation
