Answer:

When X = -1, y = -2.4

When X = 0, y = -1.8

When X = 1, y = -1.2

Step-by-step explanation:

When X = -1

3x - 5y = 9

3(-1) - 5y = 9

-3 - 5y = 9

-5y = 9 + 3

-5y = 12

y = 12/-5

y = -2.4

When X = 0

3x - 5y = 9

3(0) - 5y = 9

0 - 5y = 9

-5y = 9

y = 9/-5

y = -1.8

When x = 1

3x - 5y = 9

3(1) - 5y = 9

3 - 5y = 9

-5y = 9 - 3

-5y = 6

y = 6/-5

y = - 1.2
