Answer:
The slope of the line = m = 2
Step-by-step explanation:
Given 
The points
To determine:
The slope of this graph
Determining the slope between (0, 0) and (1, 2)
Using the formula
Slope = m =  [y₂ - y₁] /  [x₂ - x₁]
                =  [2 - 0] / [1 - 0]
                = 2 / 1  
Thus, the slope of the line = m = 2
 
        
             
        
        
        
Luis spent $9.50, in which:
Candy (y) = $1.25
Chips (x) = $0.50
$9.50 = 1.25y + 0.50x
Luis bought 10 snacks in all
10 = x + y
-----------------------------------------------------------------------------------------------------------------
You're answer:
x + y = 10
1.25y + 0.50x = 9.50
