Step-by-step explanation:
Get a line of which you want to know the slope.
Pick any two coordinates that the line goes through.
Subtract the two y-coordinates from one another.
Subtract the two x-coordinates from one another.
There is only one solution.
y = x+2
x = -1
Substitute x = -1 in y = x+2
y=-1+2
y = 1
We only get the single value of y and x so It's clear that there's only one solution.
Answer:
11.39
Step-by-step explanation:
-3.86+6.82=2.96
abs(2.96)=2.96
----------------------
4.02-12.45=-8.43
abs(-8.43)=8.43
-----------------------
1(2.96)+8.43=2.96+8.43=11.39

Answer:
20 and 25.
Step-by-step explanation:
Given:
They both teach total 45 yoga classes each week.
Erica teaches 15 fewer than twice as many as Bo.
To find:
How many classes does each instructor teach per week = ?
Solution:
Let number of classes are taken by Bo = 
Then number of classes are taken by Erica =
(given)
Total number of classes are taken by both = 45 (given)
According to the question.
+
= 45

By adding both side by 15

By dividing both side by 3

number of classes are taken by Bo =
= 20
number of classes are taken by Erica = 
= 
Therefore, number of classes are taken by Bo and Erica is 20 and 25.
