Hello!
To create a table of values, you will simply plug a value for x into the equation and then complete the table with the corresponding y-value.
For example: (x=0)
y = (-3/2)*(0) + 6 = 6
So the table would read:
x: 0
y: 6
Completing this process for several other values of x, we get:
x: -3 -2 -1 0 1 2 3
y: 10.5 9 7.5 6 4.5 3 1.5
Hope this helps, if you have any more questions I would be happy to set up a session with you!
