Y=mx+b m=slope b=y intercept or where the line crosses the y axis
slope=rise/run, from left to right
so
1. ok, so we see it is going throught (-2,1) and (-1,4) so it hits (-2,1) and then goes up 3 and right 1 so sloe=3/1 or 3 y intercept, it hits at y=7 so y=3x+7 is equation
2. we gots a hit at (0,2) and (5,6) about so goes up 4 and to the right 3 so 4/3 is slope hits y axis at about y=2 y=(4/3)x+2
