    \[y = 2x - 17 \\ y = -3x + 13\]Here is what you get doing a little work.

    To find the intersection of two lines, just solve the system of equations.

    Look closely. We know that \(y=2x−17\) and we also know that \(y=−3x+13\) so I can have them equal to each other, like \(\large y=2x−17 \text{ & } y=−3x+13 \Rightarrow 2x-17 = -3x + 13\) Is this clear?

    \[y = 2x - 17\]\[y = -3x +13\] |dw:1359305952937:dw| \[2x - 17 = -3x + 13\]

    Yeah, then plug it into any equation then solve for y.

    I am using the addition method since I know that +y-y=0

    once you find the x value, plug that into either equation to find your y value then you are done...........
