Answer:
Step-by-step explanation:
Using the slope formula (y2-y1)/(x2-x1), we get (0 - (-2)/(2-0). Simplified, this gets you (0+2)/(2-0). This is equal to 1, which means the slope is one. Putting this into slope-intercept form (y=mx+b), we can plug in (0, -2), getting us -2=0+b. b is equal to -2 then. Thus, the full equation would be y=x-2
