Question

@ivettef365 how would I find the slope intercept form, and point slope form of:
Passes through (-1, -1) and is perpendicular to y = x - 8.

Answer 1

ok to be perpendicular the slope needs to be opposite reciprocal
so you have y = x - 8 , slope = 1, so opposite reciprocal would be -1
right??

Answer 2

right

Answer 3

so the slope has to equal -1

Answer 4

now use the formula to find b, so you have y = mx + b
where y=-1. x=-1 and m = -1, so what is b

Answer 5

-2 @ivettef365

Answer 6

so my slope intercept formula would be y=-1*-1+-2?

Answer 7

no y=-1x-2?

Answer 8

right that is correct, and you can write it as follows:

y = -x -2

Answer 9

ok and what about the point slope form, y+1=-1(x+1)

Answer 10

correct

Answer 11
