Chapter 2: Q19. (page 72)

Find the slope of the line that passes through each pair of points.

7,8,1,8

Short Answer

Expert verified

The slope of the line is 0.

Step by step solution

01

Step 1- Given information

A pair of points (7,8),(1,8).

02

Step 2- Formula used

The slope formula of a line is:

m=y2-y1x2-x1

Where, m is slope of the line which is passes through the points (x1,y1),(x2,y2)andx1鈮�x2.

03

Step 3- To find the slope 

Here, (x1,y1)=(7,8)and (x2,y2)=(1,8)

So, m=y2-y1x2-x1

鈬�m=8-81-7鈬�m=0鈭�6鈬�m=0

Hence, the slope of the line is 0.
