can someone please help

Answer:
y = x-17
Step-by-step explanation:
We notice that y is 17 less than x
20 -17 = 3
36 - 17 = 19
52 - 17 = 35
y = x-17
Answer-y=x-17
Step-by-step explanation:
So as you can see, the graph shows y=3, x=20.
Using this, you can write the equation 3=20-?
and basically this is asking you what minus 20 equals 3, you can also subtract 20-3 and get 17, so the final answer should be y=x-17.
