Question

find the equation of the straight line passing through the points (3,5) which is perpendicular to the line y=3x+2

Answer 1

`y=-(1)/(3)x+6`

Explanation:

If a line is perpendicular, the slope is opposite and reciprocal of the other.

3 ---> -1/3

to find the y-int

substitute the values from the coordinates

5=-3/3x+b

5=-1x+b

b=6
