Best ResponseYou've already chosen the best response.0i suggest you plot the points and connect them with a line

Best ResponseYou've already chosen the best response.0but you can just use this . slope = (y2  y1) / (x2  x1)

Best ResponseYou've already chosen the best response.0I don't know how to do any of this that why I needed help.

Best ResponseYou've already chosen the best response.0yep slope is 2, so have you ever seen this y = mx + b?

Best ResponseYou've already chosen the best response.0m is the slope b is the y intercept

Best ResponseYou've already chosen the best response.0so can you plug the slope you found into that equation?

Best ResponseYou've already chosen the best response.0yea I know but what is the y intercept?

Best ResponseYou've already chosen the best response.0we are going to find that after you plug in the slope

Best ResponseYou've already chosen the best response.0y = 2x + b, 2 = m = slope

Best ResponseYou've already chosen the best response.0okay what do I do after that?

Best ResponseYou've already chosen the best response.0ok so we have some points on the line pick one of them to use

Best ResponseYou've already chosen the best response.0ok so we have (1, 3) that is the point where x = 1 and y = 3, so lets plug 1 and 3 into this equation y = 2x + b

Best ResponseYou've already chosen the best response.0correct so now you have everything you need for the equation y = 2x + 1
