We can solve this problem by the rule of three.
A complete pie chart has 360º. 
45º----------------------6 people
360º--------------------    x
x=(360º*6 people) / 45º=48 people.

Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 8, - 42 ) and (x₂, y₂ ) = (- 3, - 17 ) ← 2 ordered pairs from the table
m =  =
 =  =
 =  = 5
 = 5
The line crosses the y- intercept at (0, - 2 ) , then
y = 5x - 2 → C
 
        
                    
             
        
        
        
Answer:
4 + 3x
Step-by-step explanation:
Let the number = x
Product of three and a number = 3*x = 3x
Sum of four and 3x = 4 + 3x
