fill in the table using this function rule.
y=23-3x
x | y
1 |
2 |
3 |
4 |

Explanation:

Step1: Substitute x=1 into the function

$y=23-3(1)=23-3=20$

Step2: Substitute x=2 into the function

$y=23-3(2)=23-6=17$

Step3: Substitute x=3 into the function

$y=23-3(3)=23-9=14$

Step4: Substitute x=4 into the function

$y=23-3(4)=23-12=11$

Answer:

x	y
