The tables below show two functions. For each set of data: a) Determine whether the data represents a linear function, exponential function or neither and explain why. x f(x) -2 18 -1 22 0 26 1 30 2 34 x g(x) -2 2 -1 4 0 8 1 16 2 32 Rubric:

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
