Question

(20,-3) (19,-20) formula is: y2-y1/x2-x1

x1 y1 x2 y2

when i solved i got -17/-1, but my calculator says it's 17! i tried searching and it said to divide the fraction to get 17, but why do i have to divide? can someone please help me, thank u!

Answer 1

The answer would be 17 if I’m correct

Answer 2

17

Explanation:

The first thing to do is plug in the numbers for the equation. Starting with:

[-20-(-3)]/(19-20)

When you answer that you simplify the answer to

(-20+3)/(19-20)

You answer what is in the parenthesis first.

(-17)/(-1)

After this step you simplify.

17.

The answer is seventeen because any number over 1 is just the number. For example, 3/1=3. The answer is positive because the negative in the numerator and denominator cancel eachother out. leaving the answer as 17.
