Find the slope of line passing through the points (5, 9) and (5, -2)

Question

anonymous · Answer

to find the slope given two points $$(x _{1},y _{1}) and (x _{2},y _{2})$$
$$m=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }$$
m is the slope..

anonymous · Answer

so what is m?

anonymous · Answer

m will be infinite as the denominator is 0.

anonymous · Answer

can you check the question you have and see whether you typed it correctly.........

anonymous · Answer

so is the answer 11?

anonymous · Answer

no as she ^^ said, your slope would be infinite....

anonymous · Answer

so its undefined? like the slope can be any number?

anonymous · Answer

@CoconutSkies Look, y2-y1=-11 and x2-x1=0, so -11/0 is told to be infinity as it is divided by 0. Infinity is not defined, you may have to use calculus (limits) to solve so that you can get a range of values but if this question just requires formula application then it will be infinite. Google Infinity to know what it is exactly, alright?
