Answer:
Step-by-step explanation:
The slope of straight line PR where P(2,3) and R(5,-1) are two vertices of triangle PQR will be =
Therefore, the slope of the altitude passing through Q(-1,1) will be {Since, the product of slopes of two perpendicular straight line is -1}
So, equation of the altitude is where c is a constant.
Now, putting x = -1 and y = 1 in the above equation we get
⇒
Therefore, the equation of the altitude is (Answer)
This needs to be 20 characters long but it’s 4/3
