Answer 1

@shawmoes

Answer 2

what are the coordinates? that the dot is on?

Answer 3

when you figure those out you should be able to put it in the equation

Answer 4

1,-2

Answer 5

I don't really understand

Answer 6

So (1,-2) is where the dot is at right? So the 1 is the x1 value and -2 is the y1 value. So we simply put these numbers into the equation (y-y1)=m(x-x1) . Just plug them in, what do you get?

Answer 7

first blank is 1 second is -2?

Answer 8

@shawmoes

Answer 9

The first blank is already filled in as -2, what's the second blank?

Answer 10

Remember that your equation has the slope m , which we still have to find. For now what is our x1 value?

Answer 11

I'm super lost sorry @shawmoes

Answer 12

Please refer to http://www.mathsisfun.com/algebra/line-equation-point-slope.html . It might help you more :)

Answer 13

@shawmoes could you please help me get the answer I've been working on this for a while

Answer 14

OK if slope is rise divided by run, what is the slope here?

Answer 15

3?

Answer 16

@shawmoes

Answer 17

Yes that's right, so our equation is( y+2) = 3(x-1) .

Answer 18

ugh still didn't pass well ty for help

Answer 19

No problem, I am 100% sure that's the answer, so take it up with your teacher yes :) . Take care.
