Question

Which of the following is the slope between the two points (1, 5) and (6, 4)?

1/5

-1/5

5

-5

Answer 1

-1/5

Answer 2

m = (y2-y1) / (x2-x1)

Answer 3

\[slope = \frac{ y_2 - y_1 }{ x_2 - x_1 }\]

You have 2 points

(1, 5) and (6, 4)?
(x1,y1) (x2,y2)

so we can plug those numbers into that equation

\[slope = \frac{ 4 - 5 }{ 6 - 1 }\]

\[slope = -\frac{ 1 }{ 5 }\]
