Question

Line AB contains points A (8, −4) and B (1, −5). The slope of line AB is (1 point) a −7 b negative 1 over 7 c 1 over 7 d 7

Answer 1

Heya !

Given two points A ( 8 , -4 ) and B ( 1 , - 5 )

To find - slope of line AB

Solution -

`Slope = (y_(2)-y_(1))/(x_(2) - x_(1)) \\ \\ \dashrightarrow ( -5 - (-4 ))/( 1 - 8 ) \\ \\ \dashrightarrow ( - 5 + 4 )/( 1 - 8 ) \\ \\ \dashrightarrow (-1)/(-7) \\ \\ \dashrightarrow (1)/(7)`

Hence ,

Option ( c ) is correct.
