How would you graph 3 points for y=2x?

pick an x, any x,

how about x =3, then y = 2(3) = 6, I got the point (3,6)
how about x = -1, then y = 2(-1) = -2, I got the point (-1,-2)
I guess you need another one, right?

Yes, thank you

To graph points for the equation y = 2x, you'll need to choose three values of x and then substitute those values into the equation to get the corresponding y-values. Here's a step-by-step guide on how to graph these points:

Step 1: Choose three values for x:
You can select any three values for x. Let's choose -2, 0, and 2 for this example.

Step 2: Substitute the x-values into the equation to find the corresponding y-values:
For x = -2:
y = 2(-2) = -4
So, the first point is (-2, -4).

For x = 0:
y = 2(0) = 0
So, the second point is (0, 0).

For x = 2:
y = 2(2) = 4
So, the third point is (2, 4).

Step 3: Plot the points on a graph:
On a graph paper, mark your x-axis and y-axis with appropriate scales. Then, plot the three points (-2, -4), (0, 0), and (2, 4) according to their coordinates.

Step 4: Draw a line connecting the points:
Connect the three plotted points with a straight line. This line represents the graph of the equation y = 2x.

Note: Since y = 2x is a linear equation with a slope of 2, the graph will be a straight line that passes through the origin (0, 0). The line will also increase or decrease by 2 units on the y-axis for every 1 unit increase in the x-axis.
