Question

Fill in the blanks below.

Find the slope of the line passing through the points (7, 7) and (7-8).
slope:
Find the slope of the line passing through the points (-6, 7) and (9,7).
slope:

Answer 1

a) Slope of the line m = ∞

b) Slope of the line m =0

Explanation:

Explanation:-

Step(i):-

Given points are ( 7,7) and (7,-8)

Slope of the line

`m = (y_(2) - y_(1) )/(x_(2)-x_(1) )`

`m = (-8-7 )/(7-7 ) = (-15)/(0) = infinite`

m = ∞

Step(ii):-

Given points are (-6,7) and (9,7)

Slope of the line

`m = (y_(2) - y_(1) )/(x_(2)-x_(1) )`

`m = (7-7 )/(9-(-6) ) = (0)/(15) = 0`

Slope of the line m =0
