Question

Using the given points, determine the slope.

(8, 1) and (8, -4)


slope = 0
slope = -5
slope is undefined

i got -6 1/2

Answer 1

so im guessing its C

Answer 2

-4-1/8-8 = -5/0 is equals to -infinity so is undefined

Answer 3

\[\large slope=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}=\frac{-4-1}{8-8}\]

Answer 4

oh yes thanks @AzureKais i forgot tht y2 is first not y1

Answer 5

slope(m) = (y2 - y1) / (x2 - x1)
m = (-4 - 1) / (8 - 8)
m = -5/0
the slope is undefined....this is a vertical line.
