Can someone please explain to me how to find the X intercept for an equation like y=4 and the Y intercept for an equation like x=3? I completely forgot. Thanks!

If we are given an equation like y = f(x)
to get X- intercept, we plug in y=0
to get Y- intercept, we plug in x=0
For equations you mentioned,
to get X-intercept, if you plug in y=0, you get 0=4 which is FALSE!
so you can conclude, there is no X-intercept.
another way to look at this
y =4 is a HORIZONTAL line!
which is 4 units away from X axis,
and it is parallel to X-axis!
So it will NEVER meet the X-axis!
hence there will be no X-intercept :)
can you do similar analysis using both the methods for x=3 ?? :)

Ohhh, okay, I understand now. So, for x=3, it would be a vertical line three units to the right of the y-axis. Because of this, there wouldn't be a y-intercept. Correct? Thank you so much, you're a lifesaver. :)
