Question

Which of the following will give you the incorrect slope?

A: y2-y1 B: y2-y1 C: y1-y2 D: Rise
--------- -------- -------- --------
x2-x1 x1-x2 x1-x2 Run

Answer 1

Slope is equal to rise over run. The slope of the line is also equivalent to the change in y per unit change in x. It is important in calculating the change by using correspondence. In this case, the one that does not follow correspondence is B.

Answer 2

we know that

Given the points

(x1,y1) and (x2,y2)

The slope m is equal to

`m=((y2-y1))/((x2-x1))` ------> equation
`1`

Multiply by
`-1` boths numerator and denominator

`m=((y1-y2))/((x1-x2))` ------> equation
`2`

equation
`1` and equation
`2` are equivalent

So

option A) Is correct

option B) Is not correct

option C) Is correct

option D) Is correct

therefore

the answer is the option B
