What is the slope of the line through (2,−2)and(9,3)
your answer must be exact.

Slope is equal to m so the slope of (2, -2) and (9, 3) is m = 5/7

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
