Practice questions for y = mx + c
For the line y = 3x – 2, what is the gradient?
Two students write down equations for parallel lines: Student A writes: y = 2x + 1 Student B writes: y = 2x + 1 Explain why these two lines are NOT parallel to each other.

What is special about y = mx?
It passes through the origin (0, 0) because c = 0.
What gradient gives a 45° line?
m = 1 (rises 1 unit for every 1 unit across)
