Question

How would you set up the y=mx+b with (0, -5) and (3, -4)?

Answer 1

y1-y2=m (x1-x2)
so...
-5+4=m(0-3)
-1=m(-3)
m=1/3

Answer 2

What about b?

Answer 3

b is the (y) intercept, so you setup the variable (y) to 0 into the original equation

Answer 4

Can you show me? Sorry, I don't remember my algebra all that much.

Answer 5

what was your original equation?
or they are asking just for the slope?

Answer 6

They're asking for the slope, but can you find the b with that pair?

Answer 7

yes :)
it was given to you!!! remember (0, -5)
so the equation would be y=(1/3)x-5
because m=1/3 and b=-5
good luck ;) !!!!
