Question

Select the equation of the line that passes through the point (2, –1) and has slope 3 in point-slope form.

A. (y – 1) = 3(x + 2)
B. (x – 2) = 3(y + 1)
C. (x + 2) = 3(y – 1)
D. (y + 1) = 3(x – 2)

Answer 1

C?

Answer 2

@jigglypuff314
Is C correct?

Answer 3

Ok, thank you

Answer 4

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

Answer 5

So, C is not correct?

Answer 6

nope

Answer 7

Hmm.. than B?

Answer 8

then*

Answer 9

it would start with a y

Answer 10

Oh.. I still don't get it.. all we have left is A and D, and I might say A, but what if D is correct. Can you explain more?

Answer 11

point slope form: y - y1 = m(x - x1)
when m = slope and given the point (x1, y1)
so given slope=m=3
and point (2, -1)
plug in 2 = x1 and -1=y1

Answer 12

D?

Answer 13

yep :)

Answer 14

Phew :) thanks!

Answer 15

you're welcome ;)

Answer 16
