Final answer:
The coordinates of the y-intercept for the equation y=6x+4 are (0, 4), which is the point where x is 0 and y is 4.
Step-by-step explanation:
The coordinates of the y-intercept of the equation y=6x+4 can be found by determining the point where the line crosses the y-axis. This occurs when the value of x is 0. Substituting 0 for x in the equation, we get y = 6(0) + 4, which simplifies to y = 4. Therefore, the coordinates of the y-intercept are (0, 4).
