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

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

Explanation:

we know that

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

`m=(y2-y1)/(x2-x1)`

Let

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

Substitute the values

`m=(14-17)/(1-8)`

`m=(-3)/(-7)`

`m=(3)/(7)`
