I'm sure you've calculated x- and y-intercepts before. What did you do to obtain them?
OpenStudy (roguehamster2073):
ill let mathmale answer he was here first
OpenStudy (roguehamster2073):
unless u give me permission @mathmale
OpenStudy (saldis):
lol idk
OpenStudy (roguehamster2073):
Well

Ill answer
OpenStudy (saldis):
ok
OpenStudy (roguehamster2073):
You have to graph 2x+4y =12.4 first, before you can even get close to answering
OpenStudy (roguehamster2073):
on a coordinate graph, do you know how to do that
OpenStudy (saldis):
I am a blonde.... do you think I know how to do that

Well, if you go to the link I g ave, and type 2x+4y =12.4 in, its real simple

or copy/paste it in
OpenStudy (saldis):
Ok i did and idk what the line is ahahah
OpenStudy (mathmale):
Of course, graphing will help. However, I'd suggest an easier approach:
To find the y-intercept, let x=0.
To find the x-intercept, let y=0.
@ saldis: Try this approach now.
2x + 4y = 12.4
OpenStudy (roguehamster2073):
Ok grea let me explain
OpenStudy (roguehamster2073):
yes

try his first before i explain
OpenStudy (mathmale):
I'd suggest you learn to do this without the help of computer software. Check your results with such software, if you wish.
OpenStudy (roguehamster2073):
Listen to him hes expert, but leave the link i gave you open
OpenStudy (mathmale):
2x + 4y = 12.4 Let x=0; find y now, please. @saldis?
OpenStudy (saldis):
ok

i dont think she knows what the graph is
OpenStudy (roguehamster2073):
or x y
OpenStudy (saldis):
Yea your right I am a blonde I dont know what colors are either XD
OpenStudy (roguehamster2073):
Ok saldis do you still have the link I gave you with the line open
OpenStudy (roguehamster2073):
do you?

no I got the answer thank you
OpenStudy (roguehamster2073):
Great
OpenStudy (mathmale):
Still, I think you'd better learn how to find x- and y-intercepts quickly and accurately; you will need this skill in future problems.
