The correct answer is: [A]: " (134 − 35) / (16 4) " .
______________________________________________
Step-by-step explanation:
______________________________________________

One way to calculate the slope, "m", of a line is:

m = (y₂ − y₁) / (x₂ − x₁) ;
______________________________________________
We are given the two (2) points on the graph:

"(4, 35)" , and: "(16, 134)" .
______________________________________________

Thus, we have:

(x₁, y₁) ; and: (x₂, y₂) ;

We could either:

1) Use: "(4, 35)" for "(x₁, y₁)" ; and then: "(x₂, y₂)" would be: "(16, 134)" ;

in which x₁ = 4; x₂ = 16; y₂ = 134; y₁ = 35 ;

and: "m = (y₂ − y₁) / (x₂ − x₁) " ;

→ " m = (134 − 35) / (16 − 4) " ;

→ which is NOT an answer choice that is provided ;

OR:
__________________________________________________
2) Use: "(16, 134)" for "(x₁, y₁)" ; and then: "(x₂, y₂)" would be: "(4, 35)" ;

in which: x₂ = 4; x₁ = 16; y₂ = 35; y₁ = 134 ;

and: "m = (y₂ − y₁) / (x₂ − x₁) " ;

→ " m = (35 − 134) / (4 − 16) " ;
______________________________________________________
And among the answer choices provided;

"Number 1" (shown above): is the only choice which is correct; which is:

Answer choice: [A]: " (134 − 35) / (16 4) " .
______________________________________________________
→ The correct answer is: Answer choice: [A]: " (134 − 35) / (16 4) " .
