Find the slope of a line parallel to the line passing through points at
(1, -2) and (3, 2).
A. 1/2
B. undefined
C. 0
D. 2
4/2 = 2
Find the slope of a line parallel to the line passing through the given points G(0,3), H(8,7)
Find the slope of a line perpendicular to the line passing through the given points P(6, -1), W(3, -2)
To find the slope of a line parallel to another line, we need to use the fact that parallel lines have the same slope.
The formula for finding the slope between two points, (x₁, y₁) and (x₂, y₂), is given by the equation:
slope = (y₂ - y₁) / (x₂ - x₁)
In this case, the given points are (1, -2) and (3, 2).
Let's calculate the slope between these two points:
slope = (2 - (-2)) / (3 - 1)
= 4 / 2
= 2
So, the slope of the line passing through the given points is 2.
Since we are looking for a line parallel to this line, the slope of the parallel line will also be 2.
Therefore, the correct answer is D. 2.
