Question

I need help to graph the line this is a study guide check point it gives you the answer if you do not know it but I don’t want just the answer on how to do it I want the explanation of it being worked out

Answer 1

Given:

`y=2x`

To graph the given equation, we can plug in any values for x to get values for y as shown below:

Example 1:

Let x= 0

We plug in x= 0 into y=2x:

`\begin{gathered} y=2x \\ y=2(0) \\ \text{Simplify} \\ y=0 \end{gathered}`

Based on the above values of x and y, our point is (0,0).

Example 2:

We let x =2:

`\begin{gathered} y=2x \\ y=2(2) \\ \text{Simplify} \\ y=4 \end{gathered}`

It means that the point is (2,4).

Hence, the graph of y=2x is:
