What is the x-coordinate of the point of intersection for the two lines below?
Brut [27]

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

\begin{bmatrix}2x+y=-9\\ 2x-5y=-3\end{bmatrix}

solving the system of equations

subtracting 2x+y = -9 from 2x-5y = -3

2x-5y=-3

-

\underline{2x+y=-9}

-6y=6

so

\begin{bmatrix}2x+y=-9\\ -6y=6\end{bmatrix}

solving for y

-6y=6

Divide both sides by -6

\frac{-6y}{-6}=\frac{6}{-6}

y=-1

\mathrm{For\:}2x+y=-9\mathrm{\:plug\:in\:}y=-1

2x-1=-9

2x=-8

Divide both sides by 2

\frac{2x}{2}=\frac{-8}{2}

x=-4

Thus, the x-coordinate of the point of intersection for the two lines below will be:

x=-4

Also, the graph is attached.

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
