can you find the slope first? then find the y intercept?

i suggest you plot the points and connect them with a line

but you can just use this . slope = (y2 - y1) / (x2 - x1)

so is the slope 2?

I don't know how to do any of this that why I needed help.

yep slope is 2, so have you ever seen this y = mx + b?

m is the slope
b is the y intercept

so can you plug the slope you found into that equation?

yea I know but what is the y intercept?

we are going to find that after you plug in the slope

so y=2?

y = 2x + b, 2 = m = slope

okay what do I do after that?

ok so we have some points on the line pick one of them to use

pick either one

(1,3)

so 1=b?

correct so now you have everything you need for the equation
y = 2x + 1

okay thankyou!
