Question

Create a set of coordinates to model a relation that is a linear function.

Answer 1

Here’s a simple set of coordinates that model a linear function:

Use the function y = 2x − 1. Points (x, y):
- (−2, −5)
- (−1, −3)
- (0, −1)
- (1, 1)
- (2, 3)
- (3, 5)

Check: the change in y for each +1 change in x is +2 (constant slope), so these points lie on a straight line.

If you want a different slope or intercept (e.g., negative slope, fractional slope, or through specific points), tell me and I’ll create another set.
