Question

Plot .(my three key doesnt work..)
-x+three y=-6

Answer 1

-x+3y= -6

this is the equation of a line
one way to plot is find two (x,y) pairs, plot them and draw a line through the 2 points

if x=0, what is y?
if y is 0, what is x?
answer those two questions to get 2 (x,y) pairs

Answer 2

ok so -6= -x+three y

Answer 3

that is the exact same equation.
now replace x with 0. what do you get?

Answer 4

-6=-0+three y

Answer 5

do i subtract three y both sides

Answer 6

-6= -0+3y
of course -0 is the same as 0 (0 is 0)
and 0 added to anything does not change anything:
-6= 3y
to find y, divide both sides by 3

Answer 7

x=three

Answer 8

y=three

Answer 9

you have to be more careful. first, there is no x. it's y
2nd, -6/3 = -2 not +2 or +3
3y= -6

3y/3 = -6/3
y= -2

Answer 10

that means (0,-2) is on the line

now replace y with 0 in

-x+3y= -6

Answer 11

ok i do see the mistake x but its y=

Answer 12

-x+three(-2)=-6

Answer 13

i think i put th

Answer 14

no, we are done with the first part of the problem.
now replace y with 0 in

-x+3y= -6

Answer 15

the wrong number for x ok.
-x+three(0)=-6

Answer 16

yes
-x +3*0= -6
-x+0 =-6
-x= -6
if you multiply (or divide!) by -1 on both sides:
-1* -x= -1*-6
what do you get?

Answer 17

(0,6)

Answer 18

ok or x=6

Answer 19

no, be more careful
-1* -x= -1*-6
what do you get?
you get
x= 6

that means the pair is (6,0)

you now have 2 points to plot
(0,-2) and (6,0)

Answer 20

i have trouble with that swapping numbers

Answer 21

if you know that, write down (x,y) on your paper and double check
with this last one, we started with y=0 so write down (x,0) so you don't forget
then work out what x is , and fill it in: (6,0)

Answer 22

ok so th value is -three y and 6x

Answer 23

ok that i will do to help me

Answer 24

you now have 2 points to plot
(0,-2) and (6,0)

Answer 25

yes

Answer 26

ok did i get my value correct
