Question

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

graph the linear system and determine how many solutions it has.

Answer 1

... so graph each and find out where the 2 lines overlap/intersect

Answer 2

1 intersection = 1 solution
2 " = 2 "

if lines on top of each other: infinite intersections = infinite solutions

Answer 3

goku rocks!

Answer 4

who said goku cant do math?

Answer 5

;D
...wait... who DID say that...? @azbits ?

Answer 6

Superman lol

Answer 7

it's on!

Answer 8

@MysteryOwl ... assume it's meant to be x+2y=-2... yeah?

Answer 9

yes

Answer 10

cool, so what did you're lines look like on the graph?

Answer 11

how can i graph those 2 equations?

Answer 12

pick an x value
solve for y
plot that point as (x, y) on the graph
ie EQN 1: x+2y=-2 i pick x = 10
10+2y=-2
2y = -12
so y = -6

so my first point is (10, -6)

u try for equation 2...

Answer 13

also dude, if ur not understanding something, pipe up nice and early hey, that way we wont brush over bits like this

Answer 14

hmm.. i see.. its ok.. im just doing advance study.. because our proferssor might give us a surprise quiz.. and one thing im not a dude xD

Answer 15

2nd point for equation 1:
pick an x value
solve for y
plot that point as (x, y) on the graph
ie EQN 1: x+2y=-2 i pick x = 0
0+2y=-2
2y = -2
so y = -1

so my 2nd point is (0, -1)

Answer 16

so when we plot equation 1 it gives us a line that looks something like this

Answer 17

sorry little dudette ;D

Answer 18

infinite solution :D

Answer 19

perfect!

Answer 20

hihihi xDD i see now. aigatou goku-kun

Answer 21
