Answer:
a) <em>Slope of the line m = ∞</em>
<em>b) Slope of the line m =0</em>
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<u><em>Step(i):-</em></u>
<em>Given points are ( 7,7) and (7,-8)</em>
<em>Slope of the line</em>
<em> </em><em />
<em> </em><em />
<em> m = ∞</em>
<u><em>Step(ii):-</em></u>
Given points are (-6,7) and (9,7)
<em>Slope of the line</em>
<em> </em><em />
<em> </em><em />
<em>Slope of the line m =0</em>
100*2.2=220
80*2=176
220+176=396
So the two trains will take 2.2 hours so that they are 396 miles apart.
