Question

A student finds the slope of a line between (8, 17) and (1,4) she writes 17-14/1-8 what mistake did she make? A.) she used Y-values where she should've used x-values. B.) She should have added the values, not subtracted them. C.) she mixed up the x and y-values D.) she did not keep the order of the points the same in the numerator and the denominator

Answer 1

The answer is D. She should have used 8-1 as the denominator since she used 17-14 as the numerator.

Answer 2

Answer:

The answer is the option D.) she did not keep the order of the points the same in the numerator and the denominator

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

Let

$A(8,17)\ B(1,14)$

Substitute the values

$m=\frac{14-17}{1-8}$      

$m=\frac{-3}{-7}$

$m=\frac{3}{7}$
