Because we're given two points on the line, we can apply the slope formula to find the answer:

-4 - 8 / 2 - (-1)
-12 / 3
-4
<h3>The slope of the line is -4.</h3>
Answer:
<em>The student completed 13 courses worth 3 credits</em>
Step-by-step explanation:
<u>System of Equations</u>
Let's assign the following variables:
x = number of courses worth 3 credits
y = number of courses worth 4 credits
Some student completed 18 courses thus:
x + y = 18 [1]
The student earned a total of 59 credits:
3x + 4y = 59 [2]
From [1]:
y = 18 - x
Substituting in [2]:
3x + 4(18 - x) = 59
Operating:
3x + 72 - 4x = 59
Simplifying:
-x = 59 - 72 = -13
x = 13
The student completed 13 courses worth 3 credits
Answer:
C
Step-by-step explanation:
If you look at the two angles, one is 7x and the other is 11x, they appear to be next to each other and make a right angle, if you look at the bottom corner of them there is a square which means it is a right angle. this means that if you put 7x with 11x it would = 90
