Chapter 3: Q. 400 (page 353)

In the following exercises, graph by plotting points.
$2 x + y = 7$

Short Answer

Expert verified

The graph of the equation is

Step by step solution

Step 1. Given information

Equation to be plotted is

$2 x + y = 7$

It can be rewritten as

$y = 7 - 2 x$

Step 2. To find three points whose coordinates are solution to the equation

When $x = 0$

localid="1645013086203" $y = 7 - 2 脳 0 y = 7$

When $x = 2$

localid="1645013059684" $y = 7 - 2 脳 2 y = 7 - 4 y = 3$

When $x = - 2$

localid="1645013023422" $y = 7 - 2 (- 2) y = 7 + 4 y = 11$

Now arrange these points in a table

x	y	(x,y)
0	7	(0,7)
2	3	(2,3)
-2	11	(-2,11)

Step 3. Plot these points in a rectangular coordinate system

points(0,7), (2,3) and (-2,11) are plotted as

Step 4. Draw the line through three points and extend the line.

The line is the graph of the equation
