Final answer:

The y-intercept of the equation y=3x is (0, 0). This means that when x=0, the value of y is also 0. The y-intercept represents the point where the line crosses the y-axis. In this case, the line passes through the origin (0,0), so the y-intercept is at (0, 0). Option C is the correct answer.

Step-by-step explanation:

For the equation y=3x, to find the y-intercept we need to determine the value of 'y' when 'x' is zero. The y-intercept is a specific point where the line of the equation will cross the y-axis.

To find this, we simply plug 'x' = 0 into the equation: y = 3(0) = 0. Therefore, the y-intercept is at the point where y equals zero. By doing this, we have shown that the y-intercept of this linear equation is at the point (0, 0), which means the correct answer is C) (0, 0).
