Question
The line m passes through the points (-2,-3) and (4,-7). The line n passes through the points (0,3) and (6,-1). The lines m and n are ____________ lines.
- Perpendicular
- Parallel
- Collinear
- Intersecting
Hint:
In this question, we have to find the relation between line m and n. If the co-ordinates of line m are A(-2,-3) and B(4,-7) and the co-ordinates of line n are C(0,3) and D(6,-1). Firstly we will find the slope of line m and n. If the slopes of the lines are same the lines will be parallel.
The correct answer is: Parallel
The co-ordinates of line m are A(-2,-3) and B(4,-7). The co-ordinates of line n are C(0,3) and D(6,-1).
Slope of m
Slope of n
As the slope of m = slope of n
So, m and n are parallel lines.
