Solve each equation for y, then use y intercept and slope to graph
-2y=-x+3
y=x/2-3/2 this one has y intercept of (0,-3/2) from that point you use slope to graph second point, slope is 1/2 so you go 1 point UP and 2 to the RIGHT
y=-x y intercept of this one is at the origin (0,0), the slope is -1, so -1/1, so you go 1 DOWN and 1 to the RIGHT from the origin
