I really don't get this and need help!

So to graph using a table, the first step is...well... make a table. so you have a column of x and y. under the x column write down a bunch of values you would like to test. I am going to test -2 through 2.

x | y

-2|

-1|

0 |

1 |

2 |

Next, we have to plug each of those values into the equation y=2x to see what the corresponding y value is.

when x=-2 y=2(-2)=-4, when x=-1 y=2(-1)=-2, and so on...

x | y

-2|-4

-1|-2

0 |0

1 |2

2 |4

-2|-4

-1|-2

0 |0

1 |2

2 |4

Next, graph those points on a coordinate plane. Each row on the table is a point on the graph, (x,y). Hope that helps!
