To draw the graph for the given linear equation, we need to first plot the points which lie on it, join them to get a straight line. First equation is 2x−3y=6⟹y=23x−2 Substitute different values of x in the equation and calculate to get corresponding values of y.

Plot these points on the graph paper and join them using a straight line. On observing the graph, we find that the two lines intersect each other at right angle. Hence, they are perpendicular to each other.
