State whether each equation below represents a proportional relationship. how
can you tell?
a. y = x + 2.3
b. y = 6/13x
c. 7 - y = 2x

If (x + 8) is a factor of f(x), which of the following must be true? both x = –8 and x = 8 are roots of f(x). neither x = –8 nor x = 8 is a root of f(x). f(–8) = 0 f(8) = 0
