75 +10n = 15n
75 = 5n
15 = n
Therefore 15 classes
13x - 11y = -12
-13x -13x
___________
-11y = -13x - 12
___ ______
-11 -11
-13x -12
y = _______
-11
Answer:
-30
Step-by-step explanation:
To find slope, subtract two y's and then subtract the x's in the same order.
<u>12-(-18)</u>=<u>30</u>=-30
11-12 -1
You could also switch the order like this...
<u>-18-12</u>=<u>-30</u>=-30
12-11 1
As you can see, both of the ways of solving for slope resulted in -30.
Hope this helps!! Have a great day :3
