-4x + 3y = 6

mathslover (mathslover):

Do you want to solve for x ?

OpenStudy (anonymous):

how do you graph it

mathslover (mathslover):

k wait let me draw it

mathslover (mathslover):

if x = 1 then .. y = ? can u tell me this first ?

mathslover (mathslover):

@ivandelgado just put x =1 and then solve for y ..what r u getting ?

OpenStudy (anonymous):

idk ?

mathslover (mathslover):

ok .. no problem : given that -4x+3y =6 .. we put x = 1 -4(1)+3y=6 -4 + 3y=6 3y = 6+4 3y = 10 y = \(10\over 3\)

OpenStudy (anonymous):

can you draw me a pic of it

mathslover (mathslover):

@ivandelgado u mean that u want answer not solution right ?

OpenStudy (anonymous):

i just need to know how to graph it that it

mathslover (mathslover):

see what i am doing will lead u to the answer please wait

mathslover (mathslover):

put x = 3 \[\large{-4(3)+3y=6}\] \[\large{-12+3y=6}\] \[\large{3y=6+12}\] \[\large{3y=18}\] \[\large{y=\frac{18}{3}}\] \[\large{y=6}\]

mathslover (mathslover):

hence when x = 3 then y = 6 similarly when x =6 we have : \[\large{-4(6)+3y=6}\] \[\large{-24+3y=6}\] \[\large{3y=30}\] \[\large{y=\frac{30}{3}}\] \[\large{y=10}\]

mathslover (mathslover):

hence when x =6 , y= 10 now we will draw the graph
