Question

Draw the graph of the equation, y = 3x.

Answer 1

The given equation is y = 3x.
Putting x = 0, we get y = (3 × 0) = 0.
Putting x = 1, we get y = (3 × 1) = 3
Thus, we have the following table:

x	0	1
y	0	3

On a graph paper, draw the lines X'OX and YOY' as the x-axis and y-axis, respectively.

Now, plot the points A(0,0) and B(1,3) on the graph paper.
Join AB and extend it on both sides.
Thus, line AB is the required graph of the equation, y = 3x.
