The ordered pair is (-2, -3)
Step-by-step explanation:
- Step 1: To find whether an ordered pair is a solution, substitute values of x and y and see whether it satisfies the equation.
(-3, -2) ⇒ 7 × -3 - 5 × -2 = -21 + 10 = -11 ≠ 1
(-2, -3) ⇒ 7 × -2 - 5 × -3 = -14 + 15 = 1
(0, 4) ⇒ 0 - 5 × 4 = 20 ≠ 1
(4, 0) ⇒ 7 × 4 - 0 = 28 ≠ 1
So the ordered pair is (-2, -3)

the constant of proportionality
Step-by-step explanation:
proportional relationships are relationships between two variables where there are ratios equivalent. another way to think about them is that in a proportional relationship that one variable is always constant value times the other that constant is known as the constant of proportionality 
 
        
             
        
        
        
Answer:
y = 3/2  when x = 15
Step-by-step explanation:
y = k / √1+x  
2 = k / √1+8 = k/3  
k = 6  
y' = 6 / √1+15 = 6/4 = 3/2
