How many solutions does the system have?

y=-2x-4

y=3x+3

A. One solution

B. No solutions

C. Indefinitely about of solutions

Answer: one solution

Step-by-step explanation:

The two lines have different slopes, so they can't be the same line (infinitely many solutions) or parallel (no solutions). The lines intersect at

3x+3 = - 2x - 4

5x = - 7

x = - 7/5

3 (-7/5) + 3 = - 2 (-7/5) - 4

-21 + 15 = 14 - 20

-6 = - 6

The answer is one solution
