Write equations, in standard form, for the linear functions F(x) and G(x) represented by the values in the tables above.

Question

x F(x) x G(x)

0 -1 -3 1

-6 -3 3 3

-9 -4 0 2

-12 -5 -9 -1

Answer 1

The plotted points appear to be linear (and, in fact, the lines appear to be parallel).

For that reason you can take any pair of points in each function and use the 2 point formula to get the equations.

E.g.

(-1+3)/(0+6) = 1/3 = (y+1)/x

The other one is (3-2)/(3-0)=(y-2)/x
