प्रश्न
A straight line passes through the points (2, 5) and (-4, -7). Plot these points on a graph paper and draw the straight line passes through these points. If points (a, -1) and (-5, b) lie on the line drawn, find the value of a and b.
उत्तर
The graph is as follows:
From the graph, we find that a = -1 and b = -9.
