-8-2/5-4  -10/1  mx - -10/1

anonymous · Answer

mx =-10/1

anonymous · Answer

chris66 the answer is -10/1 and not just -10

anonymous · Answer

it could be, but normally I like to put rise and run

so if i answered -10/1 would the answer be marked wrong

no because it's the same thing
the only thing is is on a graph you would go up ten and over one

anonymous · Answer

ok gotcha but it stated to simplify so I would go with -10
