Which of the following coordinates for
perpendicular to
F.
H.
G.
I. (3,5)
To Select: The coordinates of P makes line OP perpendicular to the line MN.
Answer to Problem 4STP
H. P(3,2)
Explanation of Solution
Given information: Graph of the line NM and point O(-3,5).
Formula used: Use slope of a line formula
Calculation:
Find slope of the given line NM using the points (4,7) and (-2,-5)
So, slope of the given line is 2.
According to the concept negative reciprocal of 2 is
Let’s find points using slope from O(-3,5) using formula slope
From point O move down 1 unit and right 2 units.
So, the points using slope from O are (-1,4), (1,3), (3,2) and so on.
Hence (3,2) is coordinate of P.
