Can someone with knowledge see what I did wrong on number 4
also see if number 3 is right

#4.  m=0;

#3.  m =

Step-by-step explanation:

It seems right.

#4.  

Maybe your teacher wants you to write m=0; because when a fraction has a numerator equal to zero then the fraction is zero.

#3.

Maybe your teachers want you to simplify the fraction and write m =

3. The slope is 1/-2

4. The slope is 0/6 or 0

Step-by-step explanation:

Don't worry you did number 3 correctly, but you should always completely simplify your fraction if its possible. In the fraction 4/-8, the numerator and denominator are both divisible by 4 and can be simplified to 1/-2.

You used the equation for finding the slope correctly in number 4, but 8-2=6. You accidently put 7. So, the correct fraction would be 0/6. This can also be simplified because 0 divided by 6 is 0. So, the slope is 0.
