Question

i need help understanding and figuring this out
-x+2y=2
graph the linear equation and it needs three solutions

Answer 1

Put it into y=mx +b

Answer 2

yeah graphing aint my thing

Answer 3

I'll let someone else help you I don't think I'm quite on the right track haha

Answer 4

but i have to plot and have 3 different solutions to slove the same linearr equation

Answer 5

You mean just find 3 points on the graph?

Answer 6

yeah and they all have to solve the equation

Answer 7

Well if the points are on the line, they should be solutions.

Answer 8

but their isnt any on the line thats wat i hve to figure out

Answer 9

Are you given the solutions?

Answer 10

no im given the equation and i have to figure out the x and y

Answer 11

and there has to be 3 soulutions

Answer 12

What Im saying is.. Put this equation into slope intercept form y=mx+b and graph it then pick 3 points on your line that you graph and those should be solutions for your equation.

Answer 13

@jim_thompson5910

Answer 14

\[y=1/2x+1\]

Answer 15

Okay now graph it

Answer 16

1/2 is your slope and 1 in you y-int

Answer 17

is a straight line
so for that all you really need is 2 points to plot it
try setting y = 0
that way you get the x-intercept, the y-intercept is already in the mx+b equation, which is b = 1

Answer 18

if x = 0, then y is..

-x+2y=2

-0+2y=2

0 + 2y = 2

2y = 2

y = 2/2

y = 1

So we know the point (0,1) is on the line -x+2y=2

------------------------

If x = 2, then y is

-x+2y=2

-2+2y=2

2y = 2 + 2

2y = 4

y = 4/2

y = 2

giving us the point (2,2) which is also on the line -x+2y=2

Answer 19

Or you could do it there way :P

Answer 20

you keep this up for however many points you want

next you plot each point

finally you draw a straight line through every point to graph -x+2y=2

Answer 21

so my third piont is 0,4 ??

Answer 22

(0,4) is not on the line

Answer 23

4,4??

Answer 24

-x+2y=2

-4+2y=2 ... plug in x = 4

2y = 2+4

2y = 6

y = 6/2

y = 3

when x = 4, y = 3

the point (4,3) is on the line

Answer 25

o okaii that makes a whole alota since :) thanks

Answer 26

yw

Answer 27

can u help me with some more??

Answer 28

sure, one more

Answer 29

x-3y=-6

Answer 30

when x = 0, y = ???

Answer 31

2

Answer 32

when x = 3, y = ???

Answer 33

3

Answer 34

when x = 6, y = ???

Answer 35

4

Answer 36

so we have these 3 points

(0,2), (3,3), (6, 4)

Answer 37

omg U MADE THAT SO EASY FOR MEH :) thanks:)

Answer 38

I didn't do much, you did all the work lol

Answer 39

but you're welcome

Answer 40

but still u broke it down and helped meh understand it better soo thanks

Answer 41

I'm glad I helped out and that you understand it all

Answer 42

me too
