We want to see if the two given lines are perpendicular or not.
We will see that yes, the lines are perpendicular.
First, let's define a general linear equation, it is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
Two lines are perpendicular if the slope of one is equal to the inverse of the opposite of the slope of the other.
Also, if a line passes through two points (x₁, y₁) and (x₂, y₂) then the slope of the line is given as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So we can get the slopes of the two given lines, for line PQ we have:
[tex]a = \frac{3 - (-2)}{2 - (-3)} = 1[/tex]
For line RS we have:
[tex]a = \frac{-6 - (-1)}{15 - 10} = -1 = -(1/1)[/tex]
So you can see that the slope of line RS is equal to the inverse of the opposite of line PQ.
Then yes, the lines are perpendicular.
