1. Which description best describes the solution to the following system of equations?
Alisiya [41]
1. The best answer is A since a solution is where 2 lines intersect. Whether or not they intersect the x or y axis is completely irrelevant (so is whether they intersect the origin).

2. y=-x+5
-x+5=1/2x+2
-x+3=1/2x
3=3/2x
2=x

y=-(2)+5
y=3

Answer: (2,3)

3. It seems like the lines are completely on top of each other (coinciding) so there are infinitely many solutions.
