Solve for y and graph the line.

OpenStudy (anonymous):

grath?

OpenStudy (anonymous):

no need

OpenStudy (anonymous):

y=1/5x+3

OpenStudy (anonymous):

find the x and y intercepts, plot those points connect the dots

OpenStudy (anonymous):

y=-1/5x+3

OpenStudy (anonymous):

to find the y intercept put \(x=0\) and get \[5y=15\\y=3\] so you know \((0,3)\) is on the graph

OpenStudy (anonymous):

i got all these possible answers

OpenStudy (anonymous):

to find the x intercept by \(y=0\) and get \[x=15\] right away, so \((15,0)\) is on the graph plot the points, connect the dots

OpenStudy (anonymous):

geometric figure:line

OpenStudy (anonymous):

@satellite73 15 how would i graph that?

OpenStudy (anonymous):

\((15,0)\) is 15 units to the right of the origin on the x axis

OpenStudy (anonymous):

that was a mistake sorry let me try again

OpenStudy (anonymous):

|dw:1416452154169:dw|

OpenStudy (anonymous):

OpenStudy (anonymous):

thats ok, we can get another point, since your graph will not reach there

OpenStudy (anonymous):

if you make \(x=5\) then you get \[5+5y=15\\ 5y=10\\ y=2\] so plot the point \((5,2)\)

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

|dw:1416452295061:dw|

OpenStudy (anonymous):

and if \(x=10\) then \[10+5y=15\\ 5y=5\\ y=1\] so you can also plot \((10,1)\)

OpenStudy (anonymous):

|dw:1416452370614:dw|

OpenStudy (anonymous):

(5,2)?

OpenStudy (anonymous):

x + 5y = 15 you have to y by itself so subtract x to both sides 5y = -x + 15 then divde 5 by both sides and get y=-1/5x + 3

OpenStudy (anonymous):

no wait im going to re-try that

OpenStudy (anonymous):

oh no dear, that is \((2,5)\)

OpenStudy (anonymous):

ok i wait

OpenStudy (anonymous):

satellite73 (Moderator) is right (2) (5)

OpenStudy (anonymous):

OpenStudy (anonymous):

you have \((5,3)\) right 5 up 3 you want \((5,2)\) right 5, up 2

OpenStudy (anonymous):

OpenStudy (anonymous):

count the steps, including the first one

OpenStudy (anonymous):

ok now the \((5,2)\) is right the other two are not on the graph find \((10,1)\)

OpenStudy (anonymous):

right 10, up 1

OpenStudy (anonymous):

better? im sorry im bad at this

OpenStudy (anonymous):

great now we have one point \((5,2)\) correct and on the graph now lets plot another point \((0,3)\) you need at least two for the line \((0,3)\) is 3 units up on the y axis put a dot there

OpenStudy (anonymous):

way better?

OpenStudy (anonymous):

way way better now add one more point, add \((0,3)\)

OpenStudy (anonymous):

OpenStudy (anonymous):

ok got it!! take a ruler, connect the dots, go have a snack

OpenStudy (anonymous):

you should see that they line up nicely when you do this

OpenStudy (anonymous):

thank you so so much sorry for giving you a struggle

OpenStudy (anonymous):

hey np, that is why you are here, for help

OpenStudy (anonymous):

or ten? @satellite73

OpenStudy (anonymous):

to solve the equation?^

OpenStudy (anonymous):

what?

OpenStudy (anonymous):

@Yonceee

OpenStudy (anonymous):

to solve the equation

OpenStudy (anonymous):

you got the graph right? do you need to solve for \(y\) as well?
