What is the x-intercept of the line given by the equation x-4y=20 ?

Question

mrnood · Answer

First rewrite the equation so it reads
y=???

smilewithmehun · Answer

isn't it just x = 4y + 20  ? .-.

mrnood · Answer

No

There is an easier way though

x intercept is given when y=0

SO set y=0 in the equation, and solve for x

anonymous · Answer

so the answer is 0

mrnood · Answer

NO
set y=0 in the original equation - then solv eth equation for the x value

anonymous · Answer

okay your not really helping me understand how to do this problem

mrnood · Answer

Do oyu mean I am not giving you the answer?

smilewithmehun · Answer

so 
-4y = -x +20
y= -x/4 + 5
then make y = 0 and solve
Is that what you mean @MrNood ?

mrnood · Answer

YES - that is OK 

(you can do the same with the original equation x-4y=20 : just let y=0 you will then have the answer
