- Well first off 'A' and 'D' isn't correct cuz they both don't have a solution.

But the thing is that I don't know exactly what the answer is cuz of the pic only showing the corner of it and such...

Svetlanka [38]

The y-intercept of y=4x is (0, 0)

Option B is correct

<h3>Y-intercept of a linear equation</h3>

The slope-intercept of a line is given as:

y = mx + c

where m represents the slope

c represents the y-intercept

The given equation is y = 4x

To find the y-intercept, substitute x = 0 into the equation and solve for y

y = 4(0)

y = 0

Therefore the y-intercept of y=4x is (0, 0)
