Find sum of the slope of the lines passing through the following points :
`(i) (0,3)` and `(5,1)`
`(ii) (-1,2)` and `(2,5)`

Options

A. -3/5
B. 3/5
C. 7/5
D. 1

Answer

B

Explanation

We know that the slope of a line passing through the points `(x_(1),y_(1))` and `(x_(2),y_(2))` is
`m=(y_(2)-y_(1))/(x_(2)-x_(1))`
`(i)` The slope of a line passing through the points `(0,3)` and `(5,1)` is
`m=(1-3)/(5-0)=-(2)/(5)`.
`(ii)` The slope of a line passing through the points `(-1,2)` and `(2,5)` is
`m=(5-2)/(2-(-1))=1`.
