helder_edwin · Answer

this problem is similar to one you already proposed.
you should be able to do it on your own

helder_edwin · Answer

see what @HillDP just wrote

anonymous · Answer

b is the intercept m is the slope

anonymous · Answer

yea but i dont remember whhat gets plged into what after that i knw what to do

anonymous · Answer

a.y=-x+2

anonymous · Answer

*plugged

shane_b · Answer

Since @DHASHNI  posted the answer, do you at least know why that's correct?

anonymous · Answer

no i still dont knw where to plug everything in

anonymous · Answer

you can do it

shane_b · Answer

You only have two values to plug in: the slope (which is m) and the intercept (which is b).

anonymous · Answer

b is the intercept m is the slope just substitute the values

anonymous · Answer

thanks thats what i needed to knw @Shane_B

shane_b · Answer

Good luck!

anonymous · Answer

@Shane_B : i do knw it
y=mx+c is the general format of a line
where m is the slope
and c is the y-intercept

I know you know...that question was meant for @suckatmath17.  You posted the answer while we were trying to explain it to her.
