Question

The angle between two lines is 135° and the slope of one of the line is 0.5 . What is the slope of the other line

Answer 1

Answer:

either 3 Or, -1/3.

Step-by-step explanation:

we have,
M1=0.5=1/2
Angle between two lines (A)=135
M2=?
We know, angle between the two lines is given by

tanA=± (M1-M2)/(1+M1.M2)
OR, tan 135= ±(0.5-M2)/(1+0.5xM2)
By solving this equation, we get M2=3 and -1/3
So, the slope of other line is either 3 Or, -1/3.
