Question

A system of 3 equations is graphed in the xy-plane above. How many solutions does the system have?

A) None
B) One
C) Two
D) Three

Answer 1

B) One

Explanation:

The solution(s) to a system of equations is the point(s) where ALL of the equations in the system intersect. In this situation, all three intersect at the point (-1,3). Two of the graphed equations intersect at (0,4), and another two intersect at (2,0). But there's only one point where all three intersect together.
