Question

help me!!!
find solutions to graph 2x-y=-2

Answer 1

-1

Answer 2

I think.

Answer 3

POSITIVE 1 for the first part actually.

Answer 4

x=-1 you say? wait what?? I'm trying to find ordered pairs so I can graph the line.

Answer 5

Oh, I thought you where solving the equation, did not read. Sorry bout that!

Answer 6

no problem lol

Answer 7

This equation has infinite number of solutions. However, from your comment I think you're trying to graph it , right ?

Answer 8

yes

Answer 9

I just need 3 solutions and im unsure how to find them

Answer 10

@TrojanPoem

Answer 11

do you still need help?

Answer 12

ok then.

Answer 13

It can be simplified to 2x + 2
Giving these values for (x,y)
(-10,-18)
(-9,-16)
(-8,-14)
(-7,-12)
(-6,-10)
(-5,-8)
(-4, -6)
(-3, -4)
(-2, -2)
(-1, 0)
(0, 2)
(1, 4)
(2, 6)
(3, 8)
(4, 10)
(5, 12)
(6, 14)
(7, 16)
(8, 18)
(9, 20)
(10, 22)

Answer 14

but I still don't know how you got that....

Answer 15

To Graph the function:

- Isolate the variable y. (y = 2x+2)
- Pick any three points of your choice.
(Personally I pick -1, 0, 1 and if I didn't get the absolute shape I would pick -2 , 2 ... until I fully understand it)

when x = -1
y = -2 + 2 = 0

when x = 0
y = 2

when x = 1
y = 4

Answer 16

y = 2x + 2

This is a first degree function. so It will be a straight line

y = mx + b

b : y - intercept.

m : slope of the line.
