Question

Which is the best estimate of the solution to this system of equations ?

A . Close to (4,2 )
B. Close to (2,4 )
C. Close to (4,3)
D. Close to (3,2 )

Answer 1

The answer is (4,2). The solution to a system of equations is when there is an intersection.

Answer 2

A. Close to (4,2)

Explanation:

When solving a system of equations by setting them equal to one another, the resulting co-ordinates models the coordinates at which the lines intersect. In this case, from the graph, it looks like the lines cross at about 4 on the x-scale, and about 2 on the y-scale.
