How do u graph (1.5,-2) on the coordinate grid

U find 1.5 on the bottom line and when u find it, go up until u reach 2 on the side line

You find 1 and 2 on the x-axis and put a dot in the middle of those two numbers. Then, find -2 on the y-axis and put a dot there. And then connect the dots.

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
