Answer:
.
Step-by-step explanation:
A line that goes through 
and 
where 
would have a slope of 
.
The slope of the line that goes through 
and 
would thus be:
.
Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is 
.
Thus, if 
and 
denote the slope of the first and second lines in this question, 
since the two lines are perpendicular to one another. Since 
, the slope of the first line would be:
.
Given that the first line goes through the point 
, the point-slope equation of that line would be:
.
.
Substitute in 
to find the 
-coordinate of the point in question:
.

The best and most correct answer providedfrom your question about the entrance examination paper is the second option which is 2,250. The problem can be solved by:
3-1-1 : 5c3*5c1*5c1 *3!/2! = 750
<span>2-2-1 : 5c2*5c2*5c1 *3!/2! = 1500
</span>
Adding the two answers:
750 + 1500 = 2250
