Can someone me find the 3 points? i always have trouble plotting the numbers.

To find ur sets of numbers, u simply plug in any number for x and solve for y

-x - 3y = -6lets say x = 0
-3y = -6
y = -6/-3
y = 2so one set of pints is (0,2)

-x - 3y = -6...lets say x = 3
-3 - 3y = -6
-3y = -6 + 3
-3y = -3
y = -3/-3
y = 1so another set of points is (3,1)

-x - 3y = -6,ets say x = 6
-6 - 3y = -6
- 3y = -6 + 6
-3y = 0
y = 0and another point is (6,0)

so some points on ur line are : (0,2), (3,1), (6,0)
