Points of Intersection

To find the point of intersection of two lines, we can use substitution to find the x and y coordinates.

Solving the Question

We're given:


  • y = -2x + 2

  • y = x - 4

Use substitution to find x:


-2x + 2=x-4\\-2x=x-6\\-3x=-6\\x=2

Use substitution to find y:


y=x-4\\y=2-4\\y=-2

Answer

The point of intersection is (2,-2).
