Week 1: Lines – Day 3

1. Is the point (0, 0) on, above, or below the line y = 3x + 2?

2. Is the point (-1, 5) on, above, or below the line x + y = 4?

3. Do the lines y = 17x – 1 and y = 15x – 1 intersect?

4. Are the points (2, 3), (-5, 10) and (0, 5) collinear? (Collinear means they all lie on the same line.)

5. Are the points (1, 4), (2, 8), and (3, 13) collinear?
