# How do you graph the plane 2x+y=2? (3D)?

Relevance

Well first you put it in y=mx+b, or slope-intercept form

So this goes:

2x+y=2

subtract the 2x from both sides

y=-2x+2

Now you have it in slope-intercept form

Now you put one over the two like so: -1/2 is your slope 'M'

the last 2 is your y-intercept, which is stated like so

x,y

(0,2)

Idk how to create this in 3D but for 2D, you can graph this with a ti-83 or scientific calculator.

On the ti-83 you simply hit the Y= sign in the top left hand corner. then a screen will appear, type in -1/2x+2

you can type in the x by hitting the key that says "x,t,0,n"

After you have typed that in hit graph on the far right hand side of the calculator and you can see a 2D visual of your equation.

Solve for why

Slope is 2/1 y intercept is 2 draw line after making two points make plane

• Hi Laura

......... 2x + y = 2

that's a linear equation, its graph is simple straight line

it is 2D (x,y) .......... not 3D.
