Question

Fill in the blanks below.

Answer 1

Answer:

a) Slope of the line m = ∞

b) Slope of the line  m =0

Step-by-step explanation:

Explanation:-

Step(i):-

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

Slope of the line

                     $m = \frac{y_{2} - y_{1} }{x_{2}-x_{1} }$

                    $m = \frac{-8-7 }{7-7 } = \frac{-15}{0} = infinite$

                  m = ∞

Step(ii):-

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

Slope of the line

                     $m = \frac{y_{2} - y_{1} }{x_{2}-x_{1} }$

                    $m = \frac{7-7 }{9-(-6) } = \frac{0}{15} = 0$

Slope of the line  m =0
