I already know that, can you just tell me which is right and explain please?

precal · Answer

y=x-5
y=mx+b   m is your slope value and b is your y intercept

lovelyanna · Answer

Ya, I know that.. I'm still confused on how to solve it.

precal · Answer

what number is in front of x?  that is your slope value
what number does not have an x?  that is your y intercept
You really are not solving anything, you are just identifying.
