find the slope of the line containing (3,-1) and (-3,1)

Question

anonymous · Answer

The slope is determined from the following formula where "m" is the slope:$$m = \frac{ y _{1} - y _{2} }{ x _{1} - x _{2} }$$and you use your given points:$$(x _{1}, y _{1})$$and$$(x _{2}, y _{2})$$

anonymous · Answer

So, x1 = 3, y1 = -1, x2 = -3, and y2 = 1.

So you just substitute those values into the given formula.

How's this going for you?  All good now?

anonymous · Answer

i got -2/0 and my choices are m=1/3 m=-1/3 m=0 and m=3 :/ did i do it wrong?

anonymous · Answer

you should get:

(-1 - 1) / [3 - (-3)]       =       -2/(3 + 3)      =      -2/6

= -1/3
