HELP!! Identify the point (x1, y1) from the equation: y – 7 = 3(x + 2)

(–7, 2)
(7, –2)
(–2,7)
(2, –7)

Answer 1

ok this is point slope form
which is y-y1=m(x-x1)

Answer 2

the point is x1, y1

Answer 3

do you see where i'm going?

Answer 4

I think so

Answer 5

so in this equation the y1 is 7, and the x1 is -2 are you following me?

Answer 6

and when we plug that into coordinate form we get (-2,7)

Answer 7

easy :) thx for walking me through it

Answer 8

you're welcome ;)
