Question

I am not sure how to ask this 1. I need to find an equation of the line L. y=-x and L is perpendicular.
y
|3
|
(-1,1)* |
-|-|-|-|-|-|x
-3 | 3

Answer 1

y=-x has a slope of -1/1
A perpendicular line has a slope that is a negative reciprocal, so slope=1/1=1

If the line goes through point (-1,1) then we can substitute its x and y values, as well as our new found slope into our general equation of y=mx+b to find its y-int
\[(1)=(1)(-1)+b\]
\[(1)=(-1)+b\]
\[2=b\]
so our equation is:
\[y=(1)x+2\]
or
\[y=x+2\]
