The variables x, y, and z represent polynomials where x = a, y = 3a – 5, and z = a^2 + 2. what is x^2y – z in simplest form?
a. 2a^2 – 5a – 2
b. 3a^3 – 6a^2 – 2
c. –3a^3 – 2
d. –3a^2 – 2

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
