Question

Find the slope given the two points. (2, -6) and (2, 3)

Answer 1

0 (horizontal line)

Explanation:

(2,-6) (2,3)

m= 3-(-6)/ 0= 9/0= 0

Answer 2

Answer: Undefined

The x coordinates are the same, so a vertical line forms. All vertical lines have undefined slopes.

We can see it through the slope formula

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

m = (3-(-6))/(2-2)

m = (3+6)/(2-2)

m = 9/0

We cannot divide by zero, so the result is undefined.
