6. A student finds the slope of the line between (14, 1) and (18, 17). She writes . What mistake did she make?

A. She used y-values where she should have 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.

Step-by-step explanation:

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

I hope this helps!

slope is y2-y1/x2-x1

if this was set up correctly it would be 17 - 1/18 - 14

The student simply switched the places of the y change calculation.

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

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

Let

Substitute the values

3/7

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
