Question

Can someone help me?

Answer 1

Hello from MrBillDoesMath!

Answer:

(3,6) is not a point of intersection of the lines.

Discussion:

Let's  check if the supposed point of intersection,  (3,6),  is on both lines. Start by substituting x = 3 and y = 6 in the equation y = 4x -2.  This gives

y  = 4x    - 2

6  = 4(3)  - 2 = 12 -2 = 10

6 does not equal ten so the supposed point of intersection doesn't even lie on one of the lines! Hence (3,6) is not a point of intersection of the lines.

Thank you,

MrB
