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!

Best ResponseYou've already chosen the best response.1If 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, y =4, to get Xintercept, if you plug in y=0, you get 0=4 which is FALSE! so you can conclude, there is no Xintercept.

Best ResponseYou've already chosen the best response.1another way to look at this y =4 is a HORIZONTAL line! which is 4 units away from X axis, and it is parallel to Xaxis! So it will NEVER meet the Xaxis! hence there will be no Xintercept :) dw:1439019802115:dw

Best ResponseYou've already chosen the best response.1can you do similar analysis using both the methods for x=3 ?? :)

Best ResponseYou've already chosen the best response.1Ohhh, okay, I understand now. So, for x=3, it would be a vertical line three units to the right of the yaxis. Because of this, there wouldn't be a yintercept. Correct? Thank you so much, you're a lifesaver. :)
