How many solutions does this system have? x-2y=2 y= -2x+5 a. infinitely many solutions b. no solutions c. two solutions d. one solution

X - 2y = 2
-2y = -x + 2
y = 1/2x - 1slope = 1/2, y int = -1

y = -2x + 5slope = -2 and y int = 5

different slopes, different y int, means one solution <=== u have 1 solutionand these lines are perpendicular

little tip **
different slopes, different y int = one solution
same slope, same y int = infinite solutions
same slope, different y int = no solutions
