Final answer:
The x-intercept of the equation y=2x is the point (0, 0), found by setting y to zero and solving for x.
Step-by-step explanation:
To find the x-intercept of the equation y=2x, you set y to 0 and solve for x. The equation becomes 0 = 2x. Dividing both sides by 2, you get x = 0. Therefore, the x-intercept is (0, 0).
In the context of a linear equation y = mx + b, m represents the slope and b represents the y-intercept. Since there's no b value provided in the equation y=2x, it's assumed to be 0, meaning the line crosses the y-axis at the origin.
