Question

Graph the system of equations. Then determine whether the system has no solution, one solution, or infinitely many solutions. If the system has one solution, name it.

y=2x+1
y=x-2

one solution; (–3, –5)

infinitely many


no solution


one solution; (–5, –3)

Answer 1

y=11-2x x + y =15

4x − y=7 and 2x − y=15 all have one solution

x=12 − 3y 2x + y=7

3x + 9y=24 and -4x=2y + 14 have no solution

you can just put the rest in infinite solutions
