Question

How to graph 2x+3y=6

Answer 1

it would be a downward sloping straight line graph
gradient= -2/3
y intercept= 2
x intercept= 3

express in the form Y=mX+c
where m is the gradient and c is the vertical intercept.
your equation will be y=(-2/3)x + 2

hope this helps :)

Answer 2

the easiest way to graph that is to use the cover up method or some call it the intercept method. lets start by finding the x intercept: cover up the 3y with your finger or just imagine it not there. so you have 2x =6. then to get the x by itself divide both sides by 2. leaving you with x = 3. do the same thing to get the y intercept, cover up the 2x. leaving you with 3y =6, divide both sides by 3 to get the y by itself leaving you with y = 2. you now have two points to graph. when you do the cover up method one intercept is always zero. so your two points would be (2,0) and (0,3). plot those two points and connect them to get your line. it should be a downward sloping line. hope that helped.

Answer 3

Teddy is right. (I didn't see an "Agree with" option)
Just get "y" alone.

2x + 3y = 6
-2x = -2x

3y = (-2x + 6)
/3 = /3

y = -(2/3)x + 2

Give Teddy the points, or however it works.

Answer 4

plug in a number for x, solve for y
use (x,y)
ex:
2(1) + 3y=6
2+3y=6
3y=4
y=4/3
(1,4/3)

use this point with the y-intercept
(y=mx+B) -- b is the y-intercept

2x+3y=6
3y= -2x+6
y= -2/3x+2
b= (0,2)

then connect the dots

(1, 1 & 1/3) and (0,2)

Answer 5

if u had a TI graphing calculator it'd be easier it can tell u the inercepts and it can graph
