Question

A student finds the slope of the line between (8, 17) and (1, 4).

Answer 1

Answer:

D.She did not keep the order of the points the same in the numerator

and the denominator

Step-by-step explanation:

Slope of a line is given as  

$m= \frac{y_2-y_1}{x_2-x_1}$

Here we can see that the order of the points to be taken are in the same in numerator and the denominator

our student found the slope of the line between (8, 17) and (1, 4).  and She wrote $m= \frac{17-4 }{1-8}$

Hence we can see that the order is not the same . It should be

$m= \frac{17-4 }{8-1}$

Hence our answer is D.
