Answer:
B 15
Step-by-step explanation:
10 dollar + 2 hours of work 15 x 2 
 
        
             
        
        
        
Since we have a graph, we could see where '2' is on the x axis. 
Since we see that 6 is where the functions value lies, that is the answer. 
Answer: When x = 2, y = 6
        
             
        
        
        
Answer:
The x-intercept is 4
Step-by-step explanation:
We are given;
The slope of a line as -3/4
y-intercept is 3
We are supposed to determine the x-intercept;
We need to know that;
The slope of a line is given by the ratio of the change in y to the change in x 
The coordinates of y-intercept are (0, 3)
Taking the x-intercept as a, then the coordinates of x-intercept is (a, 0)
But;
slope = Δ in y ÷ Δ in x 
Therefore;

Solving for a

Therefore, the x-intercept is 4
