The function is written in slope intercept form where y=mx+b and m is the slope.
g(x)=10x+4
The m value is 10, and therefore the slope is 10.
Final answer: 10
        
                    
             
        
        
        
<em>Answer:</em>
A: represents a function
<em>Explanation:</em>
Every other option, A,  has two y for one x. 
It can be a function if there is 1x for 1y.

Answer:
(4, 0)
Step-by-step explanation:

x=4 when y=0, and in x-intercepts, we are trying to find the value of x when y=0, which is why (4, 0) is the point of interception. 
 
        
                    
             
        
        
        
We define the variables:
 p: cost of bushel of peaches
 w: cost of watermelon
 We wrote the system of equations:
 12p + 5w = 150
 15p + 8w = 198
 We can represent the system in matrix form as
 Ax = b
 Where,
 A = [12 5; 15 8]
 b = [150; 198]
 x = [p; w]
