Question

The graph below shows a line segment XY: graph of line segment XY with endpoints at negative 1 comma 3 and 1 comma negative 1 What is the slope of the line segment XY?

Answer 1

slope = (y2 - y1) / (x2 - x1)
(-1,3)....x1 = -1 and y1 = 3
(1,-1) ...x2 = 1 and y2 = -1
now we sub
slope = (-1 - 3) / (1 - (-1) = -4/2 = -1/2 <==

Answer 2

Answer: -2

Explanation:

The slope of a line passing through two points (a,b) and (c,d) is given by :-

`\text{Slope}=(d-b)/(c-a)`

Given : The endpoints of line segment XY = (-1,3) and (1,-1)

Then , the slope of the line segment XY will be :-

`\text{Slope}=(-1-3)/(1-(-1))\\\\\Rightarrow\text{Slope}=(-4)/(2)=-2`

Hence, the slope of the line segment XY = -2
