What is the slope of the line that passes through the pit of points? (3,-1) and (5,-8)?
a. 7/2
b. 22/7
c.7/22
d. -7/2

Option D

Step-by-step 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

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
