# Write the linear equation such that each point on its graph has an ordinate 3 times its abscissa

**Solution:**

Given, ordinate is 3 times its abscissa

We have to write the __linear equation__ of the graph.

The y-coordinate is times its __x-coordinate__.

So, y = 3x

When x = 1,

y = 3(1)

y = 3

When x = 2,

y = 3(2)

y = 6

Therefore, the points are (1, 3) and (2, 6)

Plotting the points (1, 3) and (2, 6) on the graph,

Joining the points we obtain a straight line AB whose equation is y = 3x

Therefore, the linear equation is y = 3x.
