To graph the proportional relationship y = 2x, you can plot points on a coordinate plane.
1. Start by choosing a set of x-values to create a table of values. Let's choose x = 0, 1, and 2.
2. Substitute each x-value into the equation y = 2x to find the corresponding y-values.
- For x = 0, y = 2(0) = 0. So, the point is (0, 0).
- For x = 1, y = 2(1) = 2. So, the point is (1, 2).
- For x = 2, y = 2(2) = 4. So, the point is (2, 4).
3. Plot these points on a coordinate plane.
- The point (0, 0) tells us that when x = 0, y = 0.
- The point (1, 2) tells us that when x = 1, y = 2.
- The point (2, 4) tells us that when x = 2, y = 4.
4. Connect the points with a straight line. Note that since this is a proportional relationship, the line will pass through the origin (0, 0).
The graph should show a straight line that passes through the origin (0, 0) and extends through the points (1, 2) and (2, 4).
