Answer:
D      A = (1/2) (y₂ - y₁)(x₃ - x₁)
Step-by-step explanation:
b = (y₂ - y₁)
h = (x₃ - x₁)
A = (1/2)bh
A = (1/2) (y₂ - y₁)(x₃ - x₁)
 
        
             
        
        
        
Answer:
y = -8x - 1 
Step-by-step explanation:
y = mx + b
7 = -8 (-1) + b   Substitute in points for x and y. Substitute -8 for m (parallel)
7 = 8 + b
-1 = b
 
        
             
        
        
        
-4 = x - 7 
-4 + 7 = x 
3 = x 
Therefore x = 3

There are 60 minutes in one hour
to find 1/6 of an hour, divide 60 by 6:
60/6=10
Jaxson played for 19 minutes 
to find 1/3 of an hour, divide 60 by 3:
60/3=20
Hailey played for 20 minutes
20>10
Hailey played video games for 10 minutes longer than Jaxson
