Question

Which is the equation for the line perpendicular to y = –x + 11 and containing P(–2, 3)? a. y – 2 = –(x – 3) b. y = –x+ 4 c. y = –x + 4 d. y = x + 4

Answer 1

Perpendicular has slope that multiplies to -1
y=mx+b
m=slope
y=-1x+11
-1 times what=-1?
what=1

y=x+b
find b
given
(-2,3)
(x,y)
inpus -2 for x and 3 for y
solve for b
3=1(-2)+b
3=-2+b
add 2 to both sides
5=b

y=x+5 is equation
