You have to use the y2-y1 over x2-x1.
So, let's plug the numbers in.
(-3,-3)
^ ^
X1 Y1
(4,0)
^ ^
X2 Y2
So, that would be
0-(-3)
——
4-(-3)
The two subtraction signs counteract and become a positive, or addition symbol. So it would be
0+3
——
4+ 3
Do the addition to get 3 over 7 or
3

Answer:
y = 541
Step-by-step explanation:
The mean is calculated as
mean = 
Mean of set A = 
= 
= 266
ratio between means = 7 : 12, then
mean of set B = 
× 266 = 456 , thus
= 456 ( multiply both sides by 5 )
1739 + y = 2280 ( subtract 1739 from both sides )
y = 541
