Question

2y + 18x = 2x(x + 9)

3(y - 4) = 9x - 12-6
Help! Please show work and match the algebraic functions to the correct graph.

Answer 1

Graph 2 is a curved graph and matches x^2 measured data.

Explanation:

Answer 2

2y + 18x = 2x(x + 9) ⇒ Graph II

3(y - 4) = 9x - 12-6 ⇒ Graph I

Explanation:

Graph II is the only non-linear function since, correctly, it is written that it is not straight, i.e. it has a varying gradient/rate of change.
