I’m on a timer can someone help we with graphing systems of equations

Consider the graph of the exponential function y=3(2)×

What will the graph look like for a system of equations that has no solution? a. the lines will be perpendicular. b. the lines will cross at one point. c. both equations will form the same line. d. the lines will be parallel.

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab
