Question

the number points of intersection of two straight line is?​

Answer 1

On the vertical line, all points on it have an x-coordinate of 12 (the definition of a vertical line), so we simply set x equal to 12 in the first equation and solve it for y. So the intersection point is at (12,33). If both lines are vertical, they are parallel and have no intersection (see below).

Answer 2

To find the intersection of two straight lines:

1. First we need the equations of the two lines. If you do not have the equations, see Equation of a line - slope/intercept form and Equation of a line - point/slope form (If one of the lines is vertical, see the section below).
2. Then, since at the point of intersection, the two equations will have the same values of x and y, we set the two equations equal to each other. This gives an equation that we can solve for x
3. We substitute that x value in one of the line equations (it doesn't matter which) and solve it for y.

• This gives us the x and y coordinates of the intersection.
