-9x=16-y equation 1
12x=-5-y equation 2
x=-5-y÷12 from equation 2
substitute this x in equation 2
so 
-9(-5-y÷12)=16-y
15+3y=64-4y
7y=49
y=7 
and then substitute this value of y in equation (x=-5-y÷12)
so x= -5-7÷12
     x=-1 
so y=7 and x=-1

babunello [35]

The y values from:

1. ₋6

2. ₋3

3. 0

4. 3

Given the x values and y value as y = 3x

1. when x = ₋2 then y = 3x

y = 3(₋2)

y = ₋6

2. when x = ₋1 then y = 3x

y = 3(₋1)

y = ₋3

3. when x = 0 then y = 3x

y = 3(0)

y = 0

4. when x = 1 then y = 3x

y = 3(1)

y = 3

therefore we get the points as (₋2 , ₋6) (₋1 , ₋3) (0,0) (1 , 3).The graph is pltted and attached.
