Chapter 4: Q. 70 (page 452)

In the following exercises, graph by plotting points.

y=-2x

Short Answer

Expert verified

The graph of the equation is

Step by step solution

01

Step 1. Given Information 

In the given exercises we have to graph by plotting points.

y=-2x

02

Step 2. Find three points whose coordinates are solutions to the equation. 

You can choose any value for x and y.

In this case since y is isolated on the left side of the equation. It is easier to choose values of x.

03

Step 3. The given equation is y=-2xFinding the point by putting the values.

x=0x=1x=2y=-2xy=-2xy=-2xy=-2脳0y=-2脳1y=-2脳2y=0y=-2y=-4

Now the points are(0,0),(1,-2),(2,-4)

04

Step 4. Plot all points in a rectangular coordinate system.Plot the points (0,0), (1,-2), (2,-4)

05

Step 5. Draw the lines through the three points.
