Answer

a) y=x-3 b)y=x/2+4 c) y=x/2-2

Work Step by Step

To find an equation with only one solution, the slope can't be the same, so we put a random slope. To find an equation with no solution, the slopes must be the same with a different y intercept. To have infinite solutions, the second equation needs to be exactly the same as the first.
