Question

What is the yyy-intercept of y=3-4xy=3−4xy, equals, 3, minus, 4, x?

Answer 1

So we are given the equation :
$y=3-4x$
In order to get the y-intercept, simply use the value x=0 in the equation like this:
$y=3-4\times0=3$
The y intercept is $y=3$

Answer 2

We can rewrite the equation given above as,
   y = 3 - 4x

This item asks us to determine the value of the y-intercept. The value is calculated by letting x of the equation be equal to zero. Applying this methodology to the given above,

  y = 3 - 4(0)
   y = 3

Hence, the y-intercept of the given function is 3.
