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
