Question

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 1

The answer is one solution

Explanation:

I tried it on khan and it was correct.

Answer 2

Answer: one solution

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
