The values that we need for x and y must be the factors of 12. therefore, assigning values for x will solve the values of y and vice versa.
Our general equation is xy=12
if x=-1 then,
(-1)y=12
y=12/(-1)
y=-12 ans. (-1,-12)
--
if x=-2 then,
(-2)y=12
y=12/(-2)
y=-6 ans. (-2,-6)
--
if x=-3 then,
(-3)y=12
y=12/(-3)
y=-4 ans. (-3,-4)
--
if x=1 then,
(1)y=12
y=12/1
y=12 ans. (1,12)
--
if x=2 then,
2(y)=12
y=12/2
y=6 ans. (2,6)
--
if x=3 then,
3(y)=12
y=12/3
y=4 ans. (3,4)
filling up the table
| x | -3 | -2 | -1 | 1 | 2 | 3 |
| y | -4 | -6 | -12 | 12 | 6 | 4 |
you can add values on the coordinate table by assigning values for x and you will determine the values of y
