a student finds the slope of a line between (14,1) and (18,17). she writes 1-17/18-14 what mistake did she make?
she substract 18 from 14 she supposed to subtract 14 from 18
Answer:
Mistake was in denominator.
Step-by-step explanation:
If a line passes through two points ( a, b ) & ( c, d )
Then slope of this line will be = \((\frac{d-b}{c-a})\)
Now we come to the question.
a student finds the slope of a line passing through ( 14, 1 ) and ( 18, 17 ) as
slope = \((\frac{1 - 17}{18-14})\)
This formula is not the form of \((\frac{d-b}{c-a})\)
Accurate answer should be
slope = \((\frac{1-17}{14-18})\)
So mistake was in denominator.
