(2,-2)(5,7)
7-(-2)= 9
5-2= 3
9/3= 3
slope = 3
(you could also calculate the slope by just counting up how many units it goes up/down when you pick a point from the x-axis and move left/right. basically counting the rise over run)
X1=-6,x2=1 that the answer
The answer is 0
-2(1/2)+1 =0
Answer:
(B) a negative correlation.
Step-by-step explanation:
If students who finish exams early tend to get better grades than students who hold on to exams until the last possible moment implies that if we collect data about time to finish an exam and the associated grade, then, for instance, for two diffent times
the corresponding grades
and
will satisty
with high probability. This is a clear example of a negative correlation.
$7.25-$2.85= $4.40
$4.40/8= $0.55
Each orange costs $0.55
