Answer:
slope = -2
Step-by-step explanation:
Slope formula:
Given points:
(3 -4) = (x1, y1)
(-2, 6) = (x2, y2)
To find the slope, input the given points into the slope formula:
Solve:
6 - (-4) = 6 + 4 = 10
-2 -3 = -5
Simplify:
The slope is -2.
The number of multiple-choice questions is 30.
The number of open-response questions is 6.
<h3>What is an equation?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 is an equation.
We have,
Number of multiple choice questions = M
Number of open response questions = N
We can make two equations.
M + N = 36 _______(1)
3M + 5N = 120 ______(2)
From (1) we get,
M = 36 - N ______(3)
Putting (3) in (2) we get,
3(36 - N) + 5N = 120
108 - 3N + 5N = 120
2N = 120 - 108
2N = 12
N = 6
Now,
Putting N = 6 in (3) we get,
M = 36 - 6
M = 30
Thus,
The number of multiple-choice questions and open-response questions is 30 and 6.

Step-by-step explanation:
Answer: It depends on the mean absolute deviation of Samantha.
Avi has a mean absolute deviation (MAD) of 5. That means the average distance of Avi's score from her mean is 5 points.
If Samantha has a higher MAD, that means that she is less consistent. If Samantha has a lower MAD, that means she is a more consistent scorer than Avi.
