Tell whether the set of ordered pairs {(1, 6), (2, 9), (3, 12), (4, 15)} satisfies a linear function. Explain.

It is nonlinear if x repeats in any of the sets

Step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
