Question

What is the slope of the line that passes through (2, 5) and (–1, 5)?

Answer 1

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

Answer 2

So....\[m=\frac{5-5}{2+1}=0\]

Answer 3

Even without calculation, the identical values of y indicate a horizontal line (slope zero).

Answer 4

okay! thanks!

Answer 5

if you plot the points you will see the horizontal line
