y=2x.

Short Answer

Expert verified

Graph of the equation y=2x:

Step by step solution

01

Given information:

The given equation is y=2x.

02

Construct a table which contains the coordinates that are the solutions to the equation : 

The given equation, y=2xhas both x and y. The y coordinates will change with respect to the x-values, since y values is dependent on the values of x.

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

y=2脳2=4
2,4
03

Plot the graph : 

Using the table given in the step 2, point the coordinates on the graph. Then join the points with the straight line.

we get the graph of the equationy=2x
