The slopes of the lines, which make an angle `45^(@)` with the line 3x -3y-25=0 is

A

`1,-1`

B

`1/2,-1`

C

`1,1/2`

D

`-2, 1/2`

Text Solution

Verified by Experts

The correct Answer is:
D
Let m be the required slope.
`|(m-3)/(1+3m)|=1`
`Rightarrow (m-3)/(1+3m) = -+1`
` Rightarrow m -3 =1 +3 m`
` or m -3 = -1-3 m`
`Rightarrow m =-2 `
` Rightarrow m= 1/2 `
