a. $y= 3x+2; y= 5x+1 $ b. $y= 3x+1; y=3x+5$ c. $y=3x+2; y=3x+2$

Work Step by Step

a. These equations have different slopes, so they will have one solution. b. These equations have the same slope and different y intercepts, so they will never intersect and will have no solution. c. These equations are the same, so there will be infinite solutions.
