Option (c)
Step-by-step explanation:
Slope of a line that passing through two points M(-1, 4) and N(2, -5),
=
=
= -()
= -
To find the line perpendicular line to MN we will use the property,
Where and
are the slopes of two perpendicular lines.
Slope of line perpendicular to MN will be,
Slope of line joining two points J(-3, -4) and K(3, -2),
Slope =
Slope of line joining two points A(-3, 2) and B(3, 0)
Slope =
Slope of the line joining points E(0, -3) and F(2, 3),
Slope = = 3
Therefore, line EF is perpendicular to the line MN.
Option (c) is the answer.
Given:
The three points are W(0,-2), I(2,0) and L(5,k).
To find:
The value of k for which the given points are collinear.
Solution:
We know that, three points are collinear if the area of the triangle formed by these three points is 0.
The three points are W(0,-2), I(2,0) and L(5,k). So,
Adding 6 on both sides, we get
Therefore, the correct option is E.
