Question

Line AB contains points A(4, 5) and B(9, 7). What is the slope of AB?

Answer 1

Answer: $\dfrac{2}{5}$

Step-by-step explanation:

We know that slope of a line that passes through P(a,b) and Q(c,d) is given by :-

$m=\dfrac{d-b}{c-a}$

Given points : A(4, 5) and B(9, 7).

Then, the slope of line AB that contains points A(4, 5) and B(9, 7) is given by :-

$m=\dfrac{7-5}{9-4}\\\\\Rightarrow\ m=\dfrac{2}{5}$

Hence, the slope AB =$\dfrac{2}{5}$

Answer 2

The answer is 2/5 which is C. You're welcome
