Answer:
Option D
Explanation:
The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.
Given any two points on the line, its slope is given by the formula
slope = Ay - By/Ax - Bx
where:
Ax the x coordinate of point A
Ay the y coordinate of point A
Bx the x coordinate of point B
By the y coordinate of point B
The points are (3,-1) and (5,-8).
slope = -8 - (-1)/5-3 = -7/2
