Answer:
2
Step-by-step explanation:
Slope equation: (y2-y1)/(x2-x1)
y2 = 4, y1 = -2, x2= 5, x1 = 2
4 – -2 = 6
5 - 2=3
6/3 = 2
Answer:
Step-by-step explanation:
Isolate the x. Note the equal sign, what you do to one side, you do to the other.
Subtract 2/4 from both sides
x + 2/4 (-2/4) = 8/4 (-2/4)j
x = 8/4 - 2/4
Simplify
x = (8 - 2)/4
x = 6/4
Simplify. Change the improper fraction into mixed fraction
x = 6/4 = (4/4 + 2/4) = 1 2/4
1 2/4 simplified = 1 1/2
1 1/2 is your answer

Answer:
This is a Retrospective study
Step-by-step explanation:
Retrospective study is a study that compares two groups of people; those with disease or condition under study and a very similar group of people who do not have the disease or condition.
Here they are compring those men with high blood pressure who drank and those with no high blood pressure and don't drink.
Lucy would save $114.
Step 1: Multiply 6.175 x 30 = 185.25
Step 2: Divide 370,000/185.25 = 1,997
Step 3: Repeat Steps 1&2 but with (6.55 x 30) and divide 370,000/196.5 = 1,883.
Step 4: Subtract 1,997 - 1,883 = 114
Step 5: She will save $114 with points versus without.
