Question

Two lines, P and Q, are graphed:

Line P is drawn by joining ordered pairs negative 8,15 and 6, negative 12. Line Q is drawn by joining ordered pairs 4,16 and negative 9,10

Determine the solution and the reasoning that justifies the solution to the systems of equations.

(0, 8), because this point is true for both equations
(0, 8), because the lines intersect the y-axis at these points
(−2, 4), because this point makes both equations incorrect
(−2, 4), because it is the point of intersection of the two graphs

Answer 1

Answer: (-2,4)

Step-by-step explanation: I did the test and it was right

Answer 2

(−2, 4), because it is the point of intersection of the two graphs

Explanation:

we know that

When you solve a system of linear equations by graphing, the solution of the system is the intersection point both graphs.

In this problem Line P and Line Q intersect at point (-2,4)

therefore

The point (-2,4) is the solution of the system (makes true both equations)
