Chapter 3: Q.15 (page 251)

In the following exercises, graph by plotting points.
$y = 2 x$

Short Answer

Expert verified

The graph of the equation is

Step by step solution

Step 1. Given Information

Given equation is $y = 2 x$

The graph of the equation is to be determined plotting points.

Step 2. Find the points

A graph a linear equation two points are required and a third point would verify if the graph is correct i.e. if all the three lie on the same line then the graph is correct.

To determine the points, plugging x values and the corresponding y values are to be calculated.

Plugging $x = 0$ :

$y = 2 x y = 2 (0) y = 0$

Plugging $x = 1$ :

$y = 2 x y = 2 (1) y = 2$

Plugging $x = 2$ :

$y = 2 x y = 2 (2) y = 4$

Hence the points are $(0, 0), (1, 2), (2, 4)$

Step 3. Plotting the points

Plotting the points on the rectangular coordinate plane and joining them using a line:

Step 4. Conclusion

The graph of the equation by plotting points is
