2x+y=1

9x + 3y = -3

the x-coordinate of the point of intersection is

-2
0
5

The x-coordinate of the point of intersection is -2

Step-by-step explanation:

Here we have a typical system of linear equations whose solution will give us both the x- and the y- coordinates (i.e. the intersection point).

Let us solve the system and find which matches the available options, as follow. Given:

Taking the first expression and re arranging to solve for we have:

      Eqn.(1)

Plugging in it, in the second expression we then have

So finally plugging in the y value in Eqn.(1) we have

The x-coordinate of the point of intersection is -2
