Introduction To Graphs

Question
CBSEENMA8003539
Wired Faculty App

Draw a line passing through (2, 1) and (1, 2). Find the coordinates of the points at which this line meets the x-axis and y-axis.

Solution

On plotting the given points A(1, 2) and B(2, 1) on the same graph and joining them, we get a straight line AB. When we extend the line AB on both sides, we find that it intersects the x-axis at C(3, 0) and the y-axis at D(0, 3).
