    \[y=-2x+3\] To skectch; find the \(x\) intercept and \(y\) intercept. \(y\)-interecept: \(x\) = \(0\) \(x\)-intercept: \(y\)\=\(0\)

    I'm asking how I would work the equation out and do the whole (-1, 1) thing.

    sorry i didnt see it was -2, i thought it was positive 2.................after you find the "b" you go down 2 (to the right)

    Why did my negative 2 become positive, and where did (2, -1) come from -_-

    So I basically put 1 over the number with the x next to it. +3 = 3, and 2x = 1/2x which means down 2, and over one, which will give me the correct answer.

    which is why i started off with (0,3).......it doesnt lie on the x-axis [x,y] < the 3 replaces the y.
