I believe the fastest way to solve this problem is to take any two of the given points and to find the slope and y-intercept of the line connecting those two points.  

Let's choose the 2 given points (-3,16) and (-1,12).
Going from the first point to the second, the increase in x is 2 and the increase in y is actually a decrease:  -4.  Thus, the slope of the line connecting these two points is m = -4/2, or m = -2.

Now use the slope-intercept formula to find the y-intercept, b.

One point on the line is (-3,16), and the slope is m = -2.

Thus, the slope-intercept formula y = mx + b becomes 16 = -2(-3) + b.
Here, b comes out to 10.

So now we have the slope and the y-intercept.  Write the equation:

y = mx + b becomes y=-2x+10.  Which of the four given answer choices is the correct one?

What is the slope of the line that passes through the pair of points (2,12 and (6,11?
Sedaia [141]

slope = difference in y / difference in x

slope = 12 -11 / 2 -6

slope = 1 / -4

slope = -1 / 4 or

-.25

A teacher summarizes grades on an exam by,Min = 26, Q1 = 67, Q2 = 80, Q3 = 87, Max = 100, Mean = 76, Mode = 100, Standard deviat
chubhunter [2.5K]

we have

Min=26

Q1=67

Q2=80

Q3=87

Max=100

Mean=76

Mode=100

standard deviation=76

IQR=20

so

In this problem

the mean is equal to the standard deviation

therefore

<h2>The standard deviation is incorrectly</h2>
