On a recent math test, the class scored grades between 72% and 100%. write an inequality that models the range of class test grades if x represents a student's test grade.

72-100=x which is the grade

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
