Y = -1/2x - 1
Tell me if you need explanation
Answer:
Each time, the x is being multiplied by -3 to result in the output.
So for every x input, multiply by -3.
For the y output for 15, you would divide by -3 to find the input x
For example, when 7 is the input, multiply by -3, and the output y would result in -21.
3/2x - 4 = 16
Add 4 to both sides.
3/2x = 20
Multiply by 2/3.
x = 13 1/3
