Module 1. Mathematics

Two lines with equations y = 3x-6 and y = 3x + 4

  • meet when y = 3.
  • are at right angles.
  • are parallel.

Explanation

Both lines have the same gradient of 3 but different y-intercepts (-6 and +4), so they never meet and run parallel. Lines are at right angles only when the product of their gradients is -1, which is not the case here.
