x_{1}=1
x_{2}= 3
y_{1} =14
y_{2}=4
Slope= \frac{rise}{run} = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } = \frac{4-14}{3-1} = \frac{-10}{2} =-5


answer: The student flipped the y values

How do you do these 4 questions and the reasons?
Afina-wow [57]

Step-by-step explanation:

"There are several flights that have very long delays."

True.  On the boxplot, we can see several outliers greater than the maximum.

"More than 25% of flights are either exactly on time or arrive early."

False.  According to the 5 number summary, 25% of the flights are between -55 and 13.  So less than 25% of the flights are on time or early.

"About 50% of flights are delayed between 13 and 35 minutes."

False.  According to the 5 number summary, 25% of the flight times are less than 13 minutes, and 50% of the flights are less than 35 minutes.  So 25% of the flights are delayed between 13 and 35 minutes, not 50%.

"About 25% of flights are delayed by more than 78 minutes."

True.  According to the 5 number summary, 75% of the flights are delayed less than 78 minutes.  Which means 25% of the flights are delayed more than 78 minutes.

A line passes through the point (8,7) and has a slope of negative 3/4 Write an equation in slope-intercept form for this line.
Anton [14]

Answer: Y= -3/4x+13


Step-by-step explanation:

A line passes through the point (8,7) and has a slope of negative 3/4 Write an equation in slope-intercept form for this line.

This is what i get

Slope of a line Y= mx+b

Y= 7

X= 8

M= -3/4


7= -3/4(8)+b

7= -6+b

7+6=b

13=b


Y= -3/4x+13
