Answer:
From the graph, it is clear that the point of intersection is:
- (x, y) = (-4, -1)
And the x-coordinate of the point of intersection for the two lines is:
- x = -4
Step-by-step explanation:
- As we know that the solution of the system of equations is the point of intersection. Let us solve it.
Given the system of equations
solving the system of equations
subtracting 2x+y = -9 from 2x-5y = -3
so
solving for y
Divide both sides by -6
Divide both sides by 2
Thus, the x-coordinate of the point of intersection for the two lines below will be:
Also, the graph is attached.
