Use the formula:
\[m=\frac{ y _{2}-y_{1} }{ x_{2}-x_{1}}\]
OpenStudy (anonymous):

2/7?
OpenStudy (anonymous):
is it the 2?
OpenStudy (anonymous):
No, you might want to rewrite the expression, since your parnthese are probably messing up your order of operations
OpenStudy (anonymous):
also make sure all of your signs are correct
OpenStudy (anonymous):
well ik that when u have a pos. and a neg. on bottom that u change the neg. and the minus sign on bottom to pos. # and addition sign

yes, retry the problem and be careful to write it properly
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
so m=-6-8/-3+4?
OpenStudy (anonymous):
that looks write but make sure to use parentheses to do the correct operations first
OpenStudy (anonymous):
so im doing -6-8 is 2 and -3+4 is 1 thats what im getting and since its wrong what is the wrong step that im making...?
