We notice that for x = 2 , or x = 4, the value of y=0 (x intercept),
replace x by any of the latter value in y=a(x-3)² -1
===> 0= a( 2-1)² - 1====>a=1
(1,1) because x + 2y <4
=1 + 2(1)
= 3 which is less than 4
If you're talking about the soccerball to football one, it would be a
It will show a negative linear correlation between x and y
