Question

Write an equation in point slope form, that passes through points (3, -10) and (-5, -2).

a) y-10=x-3
b) y+10=-(x-3)
c) y+10=2(x-3)
d) y-10=1/2(x-3)

Answer 1

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

Answer 2

You need to find the slope first. Use \[m=\frac{ x2-x1 }{ y2-y1 }\]

Answer 3

So we can eliminate a and d

Answer 4

slope is -1

Answer 5

The slope is -1

Answer 6

so b?

Answer 7

Yes.

Answer 8

yes I think B is correct ^_^

Answer 9

i mean b sorry i am sooo busy

Answer 10

Okay, thanks y'all!
