What is the slope for (8,-2) and (7,-2)

Question

hartnn · Answer

The slope of the line through points (x1,y1) and (x2,y2) is given by :
$\huge m=\frac{y_1-y_2}{x_1-x_2}$
now,just put the values and find m.

i got  -4/1

anonymous · Answer

I feel like that is not right

hartnn · Answer

what is y1 and y2 ??

anonymous · Answer

-2,-2

Take a look at this link it WILL help you! http://cs.selu.edu/~rbyrd/math/slope/

hartnn · Answer

$y_1-y_2 = -2-(-2) = -2+2 =0$

hartnn · Answer

your numerator itself is 0!
so what would be the slope ?

anonymous · Answer

so 0/1 automatically is a slope of 0 because of the numerator!

texaschic101 · Answer

slope = (y2 - y1) / (x2 - x1)
(8,-2)...x1 = 8 and y1 = -2
(7,-2)...x2 = 7 and y2 = -2
now we sub
slope = (-2 - (-2) / (7 - 8)
slope = (-2 + 2) / -1
slope = 0/-1

if the 0 is in the numerator of the fraction, then it is a horizontal line with a slope of 0.

gotcha. Thank you so much. this was very helpful

texaschic101 · Answer

if 0 would have been in the denominator, then it would have been a vertical line with a slope undefined

hartnn · Answer

thats correct :)
slope = 0
