Answer:
(-1,1)(0,4)(2,7)(3,7)
Step-by-step explanation:
the arrows point from the x coordinate to the y coordinate in each in pair
 
        
             
        
        
        
Answer:-1
Step-by-step explanation:3-4=-1
 
        
                    
             
        
        
        
So she earned 84 total dollars
she earned 14 dollars mowing lawns
she earned (total-mowing lawns=babysitting) 84-14=70 dollar babysitting
7 dollars per hour so 
70/7=10 so 
h=10
        
             
        
        
        
Answer:
(a) rate of change = 8
(b) Function: y = 8x
(c) Domain: 0 ≤ x ≤ 2
     Range: 0 ≤ y ≤ 16
Explanation:
Looks like a inverse variation sequence.
Inverse Variation formula: y = k(x)
Take two points: (1, 8), (2, 16)
Find the value of k which is constant also considered as <u>rate of change</u>.
<u>Insert values</u>:
===========
Equation: y = 8x
Domain lies in the x axis, Range lies in the y axis.
