Answer and Explanation

Your Answer is

Correct Answer is B

Explanation

For two straight lines in the Cartesian coordinate system, in order to find the x coordinate of the intersection point, the nature of the intersection point (on two straight lines at the same time) can be used to make the y of the two formulas equal and eliminate y: y=2x+ 6, y =3x+4 2x+6=3x+4 x=2

That is, at the intersection point, the coordinate of x is 2, and the answer is B.
