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)

Answer: 1 1/3
Step-by-step explanation: 7/15 plus 9/15 plus 4/15 equals 20/15 or 1 5/15. 5/15 divided by 5 equals 1/3. So the simplified answer is 1 1/3
Answer:
-9
Step-by-step explanation:
Adding a negative 3 is the same as subtracting 3, so if you do -6 - 3 you get -9
