Lines p contains points a (-7,-9) and b (4,0) . line q is parallel to line p . line r is perpendicular to line q. what is the slope of line r? explain

Slope of p & q = 9/11 [m=(y2-y1)/(x2-x1)]
Perpendicular = opposite reciprocal
q=-11/9

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
