what is the slope of a line that crosses through the points (-4,-5) and (6,8)

Question

anonymous · Answer

Slope is:$$\frac{ y _{2} -y _{1}}{ x _{2}-x _{1} }$$

anonymous · Answer

x1: -4
x2: 6
y1: -5
y2: 8

Now fill in the values to solve.

anonymous · Answer

i dont understand it isnt the formula y+mx+b

anonymous · Answer

I think that there may be more than one formula, but this one works as well. $$\frac{ 8-(-5) }{ 6-(-4) }$$This is just the same thing as I said before, but I put the values in for you.

anonymous · Answer

after that do we square it and and then square root???

anonymous · Answer

No, just solve the equation on the top and bottom of the fraction bar. I'll do it for you this time, but I want you to let me know if you don't understand. 

8-(-5)=13
6-(-4)=10

Then we divide them.

13/10=1.3, or: $$1\frac{ 1 }{ 3 }$$So, the slope if the line is 1.3 or 1 1/3. Let me know if you need further help.
