Answer:
If its asking you to round to the nearest tenths place then its 0.2
remember that if the number you're using to round is 5 or higher you add 1. If its 4 or lower it stays the same
Given:
The equations of lines are


To find:
The relation between two of lines.
Solution:
The slope intercept form of a line is

Where, m is slope and b is y-intercept.
We have,
...(i)
...(ii)
Equation (i) can be written as
...(iii)
On comparing (i) with slope intercept form, we get

On comparing (iii) with slope intercept form, we get

Now,


The product of slopes of both lines is -1. We know that the product of slopes of two perpendicular lines is -1.
Therefore, the given lines are perpendicular.
