Question

HELP PLEASE...MEDAL FOR CORRECT ANSWER


(-1, 3) and perpendicular to y = -one thirdx + 7.

y = 3x - 12

y = 3x + 6

y = 3x - 6

y = 3x

Answer 1

I think it's the first one

Answer 2

7 doesn't go into 6 nor 3

Answer 3

to be perpendicular the slope needs to be opposite reciprocal, and you have slope of -1/3, so the opposite reciprocal = 3

so use formula y = mx + b, substitute the (x,y) with (-1,3) to find value of b

Answer 4

so you have y = 3x + b
3 = 3(-1) + b what is b ??

Answer 5

???

Answer 6

6?

Answer 7

ok, so you have the equation m= 3 and b = 6
so you have y = 3x + 6

Answer 8

ok thank you!

Answer 9

yw :)
