Match the system of equations to the number of solutions it has.(4 points)
y = 2/3x - 1 and y = 2/3x - 2
y = 5x + 7 and 3y - 15x = 18
3x + 6 = y and y = -1/3x - 4
x - 2y = 6 and 3x - 6y = 18
No solutions
One solution
Infinite solutions
y = 2/3x - 1 and y = 2/3x - 2 --> One solution
y = 5x + 7 and 3y - 15x = 18 --> No solutions
3x + 6 = y and y = -1/3x - 4 --> Infinite solutions
x - 2y = 6 and 3x - 6y = 18 --> One solution
