what is the x-intercept of y=-4x, when y=0?

Question

anonymous · Answer

The x-intercept is the location or locations on the curve where y=0.

In this case, you can easily find the x-intercept by plugging in y = 0 on the right side:

y=-4x
0=-4x

Now divide both sides by negative 4:
0/-4 = x

Zero divided by any constant is always simply 0.
0 = x

Flip the sides, so x is presented on the left. (it is still the same equation)

x=0

Therefore, we know that the x-intercept is at x = 0, or the equation has an x-intercept of '0'.
