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:
.

1)
2)
y'=-8x+20=0 ==> x=20/8=5/2
and y=-4*(5/2)²+20*5/2-6=-25+50-6=19
