Step-by-step explanation:
The slope formula is
(1)
Two points are (-2,5) and (1,4).
Therefore option D is correct.
(3)
The pair of points (6, y) and (10, -1). The slope is .
Therefore option B is correct.
(4)
For vertical line the x coordinates always remains the same. Therefore when we subtract the same number we get zero in the denominator, therefore the value of slope is undefined for a vertical line.
Therefore option D is correct.
(5)
Two points from the table are (2,110) and (3,165).
Therefore option D is correct.
