Best ResponseYou've already chosen the best response.0. . . . so i plug in the x and ys?

Best ResponseYou've already chosen the best response.1actually, you don't need to solve for "y: since you're asked to leave it in pointslope form anyhow

Best ResponseYou've already chosen the best response.1plug in \(x_1\ and\ y_1\) and the found slope

Best ResponseYou've already chosen the best response.1so.. find the slope first

Best ResponseYou've already chosen the best response.0. . . and how do i do that

Best ResponseYou've already chosen the best response.1\(\bf slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}{\color{blue}{ y_1}}}{{\color{red}{ x_2}}{\color{red}{ x_1}}}\)

Best ResponseYou've already chosen the best response.0so i plug it in like i said or just x 1 and y 1

Best ResponseYou've already chosen the best response.1they do have a value, it's given in coordinates

Best ResponseYou've already chosen the best response.0and then i just divide them?

jdoe0001

Best ResponseYou've already chosen the best response.1or leave them as fraction, yes

Best ResponseYou've already chosen the best response.1well... don't miss the "  " in front of the 33 so is 3 so, that's the slope, so plug that in, along with \(x_1\ and\ y_1\)

Best ResponseYou've already chosen the best response.0wait so what do i do with the 3?

Best ResponseYou've already chosen the best response.1x(2) => x+2 so... bear in mind that

Best ResponseYou've already chosen the best response.0so do i add 15 to the 3? to get y

jdoe0001

Best ResponseYou've already chosen the best response.1well... if you need it in "slopeintercept" form, yes, you could solve for "y:, yes BUT you're asked to leave it in "pointslope" form :)
