Chapter 3: Q.10 (page 251)

In the following exercises, graph by plotting points.

y=x-3

Short Answer

Expert verified

The graph of the equation is

Step by step solution

01

Step 1. Given Information

Given equation isy=x-3

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

02

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:

y=x-3y=0-3y=-3

Plugging:

y=x-3y=1-3y=-2

Plugging:

y=x-3y=2-3y=-1

Hence the points are0,-3,1,-2,2,-1

03

Step 3. Plotting the points

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

04

Step 4. Conclusion

The graph of the equation by plotting points is
