Question

Graph the proportional relationship y=2x by plotting points.

Answer 1

Here's the graph of the proportional relationship y = 2x:

|x | y |
|--|---|
|0 | 0 |
|1 | 2 |
|2 | 4 |
|3 | 6 |
|4 | 8 |
|5 | 10|

To plot the points, you can choose any suitable scale for the x-axis and y-axis. For this example, each unit on both axes represents one unit.

After plotting the points (0, 0), (1, 2), (2, 4), (3, 6), (4, 8), and (5, 10), connect them using a straight line:

```
|
11 *
|
10 |
|
9 |
|
8 *
|
7 |
|
6 *
|
5 |
|
4 *
|
3 |
|
2 *
|
1 |
|*
|__________
1 2 3 4
```

This line represents the proportional relationship y = 2x. As x increases, y increases at a constant rate.
