Answer:
8
Step-by-step explanation:

 × 8
 × 8
= 3
In algebra:
 × y = 3
 × y = 3
y = 3 ÷ 
y = 8
 
        
             
        
        
        
93.75 because 5.75x7.50=43.125 and 6.75x7.50=50.625 and 50.625+43.125=93.748 and round it to the near test hundredth because it’s money and that’s 93.75
        
             
        
        
        
Look at points (0, -1) and (1, 5).
m = (y2 - y1)/(x2 - x1) = (5 - (-1))/(1 - 0) = 6/1 = 6
Slope = 6
Answer: 6
 
        
             
        
        
        
The expressions in which the numbers, or variables, or both, are connected by operational signs (+, - etc.) are called algebraic expressions. For example 5, 4x, a+b, x−y.
