Consider the algebraic expression: -z-7y+18x+4 which of the follow is a constant in this expression? which of the following lists all the coefficients in this expression?

Which of the following points is collinear with (-2,1) and (0,3)

Identify the function that contains the data in the following table: x     -2         0         2         3         5     f(x)     5         3         1         2         4     possible answers: f(x) = |x| + 1 f(x) = |x - 2| f(x) = |x - 2| - 1 f(x) = |x - 2| + 1
