Question

PLEASE HELP!!

Find the slope of the line segment that contains the two points. (-18, -20) and (-18, -15)
A. -5
B. None
C. -2/5
D. Undefined
E. 36/35

Answer 1

The formula for slope is
`(y_2-y_1)/(x_2-x_1)` where x₁=-18, y₁=-20, x₂=-18, y₂=-15. We can quickly see a problem that both x values are -18, which implies that this is a vertical line. Since both x values are the same, which go on the bottom and result in a denominator of 0, the slope is undefined
