Answer 1

point slope form: y - y1 = m(x - x1)
when m = slope and given the point (x1, y1)

slope = -1/2
point: (-1, 3)

Answer 2

So, its either A or B...

Answer 3

it is A

Answer 4

Is that true, Emily?

Answer 5

it's not A...

Answer 6

but I got y = -1/2x + 3 for the slope intercept form of the graph

Answer 7

Now I'm getting confused..

Answer 8

they want it in point-slope form @CloverRacer

Answer 9

ohh okay that's easy! hold on

Answer 10

...?

Answer 11

So its B then?

Answer 12

yep :)

Answer 13

Thanks :) I have one last one. I'll close this one and ask
