Answer:  
- 7 / 4
Step-by-step explanation:
( x1, y1 ) = ( 1, 10 )
Here,
x1 = 1
y1 = 10
( x2, y2 ) = ( 5, 3 )
Here,
x2 = 5
y2 = 3
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
 
Slope = ( 3 - 10 ) / ( 5 - 1 )
Slope = - 7 / 4
Proper fraction = - 7 / 4
 
        
                    
             
        
        
        
Answer: 1 cup of sugar
Step-by-step explanation:
A recipe for banana bread requires 3 cups of bananas for every 1 1/2 cups of sugar used.
Converting 1 1/2 cups of sugar to improper fraction becomes 3/2 cups of sugar. 
If 3 cups of bananas is required for 3/2 cups of sugar,
x cups of bananas will require 1 cup of sugar
3x / 2 = 3
3x = 6
x = 6/3 = 2
Therefore, 
2 cups of bananas will require 1 cup of sugar.
We are looking for the number of cups of sugar that would require 2 cups of bananas.
We already got the answer.
1 cup of sugar would be used if 2 cups of bananas are used.

Answer:
The numbers are -15 and 100

Step-by-step explanation:
we have

Solve the left side

so

equate the numerators and the denominators
20+x=5 ------> x=5-20=-15
100=y -------> y=5
therefore
The numbers are -15 and 100
