Work Step by Step

If possible, write in the form $\quad y=mx+b$ $y-x=0$ $y=x\qquad(+0)$ slope: 1, y-intercept: 0. Graphing when we know m and b: Write m as a fraction, positive denominator, $m=\displaystyle \frac{\pm u}{v}.$ Start from $(0,b)$. Move v units to the right, and u units up or down, depending on the sign. In this way you arrive at a second point, which is enough to define a line. $m=\displaystyle \frac{1}{1}$ $(0,0)\rightarrow(0+1,0+1)=(1,1)$
