Graph the equation and you will understand why

For x intercept (where the graph crosses x-axis) plug in 0 for y.

for y intercept (where the graph crosses y-axis) plug in 0 for x.

Try it in a reply and I will correct you. - Jun 22nd 2005, 05:18 PMHayabusa
(15)2*0+4*0=8

my answer: 1.875 - Jun 22nd 2005, 05:32 PMMathGuruintercepts
You need to solve x and y intercept seperately.

First set x = to zero and solve for y:

2*0+4y=8

4y=8

y=2 <---answer for x-intercept

then set y = 0 and solve for x

2x+4*0=8

2x=8

x=4 <---answer for y-intercept

Graph the equation and see if you understand what it is we are solving for. Understand that the equation crosses the x axis when y = 0 and vice versa. - Jun 23rd 2005, 02:53 PMHayabusa
