The graph shows two lines, a and b. part a: how many solutions does the pair of equations for lines a and b have? explain your answer. part b: what is the solution to the equations of lines a and b? explain your answer.

Part A , the solutions would be where the line lines cross each other, since these lines only cross each other once, there would be one solution

Part B, the solution is where the lines cross, these lines cross at X = 3 and Y = 4 so the solution is (3,4)
