Can you put a picture of the question so that i can help you out
Answer:
Step-by-step explanation:
So the sign means that y has to be less than or equal to x plus 9
if you wanted an answer an example could be
y = 1
x = 10
this works because if implemented into the equation
1 ≤ 10 + 9 which is true
a = ( 1 , 6 )
b = ( 4 , 9 )

Now just need to put the coordinates in the above equation :



And we're done...♥️♥️♥️♥️♥️
