Can you specify which section of working is for which question?

[errant coral]

the first one is for the 2nd and 3rd image,
second is for the last image
third is for the first image

[indigo shell]

For the second question, it should be $\frac{5-(-5)}{0-(-8)}$

Same thing for the third question

First question you made a sign error, it should be $\frac{-30-(-25)}{-10-0}$.

I got the same answer for the third question,-1/2

How did you simplify?

[errant coral]

I got -5/-10

[indigo shell]

A negative divided by a negative yields a positive number

You can think of it as the negatives canceling out

[errant coral]

ohh okay

[indigo shell]

$\frac{-5}{-10}=\frac{(-1)(5)}{(-1)(10)}=\frac{5}{10}=\frac{1}{2}$
