What is the slope of the line passing through (-3, 5) and (5, -3)?
Solution:
Given points are (x1, y1) = (-3,5)
(x2, y2) = (5, 3)
Slope, m = (y2 - y1)/(x2 - x1)
m = (-3 - 5)/(5 - (-3))
m = -8/8
m = -1
Note:
Slope of the line can also be calculated if the angle(θ) made by the line with positive direction of x axis is given using slope = m = tan θ
Example:
If the line makes an angle 30° with the positive direction of the x axis then find the slope.
Solution:
Slope of line = m = tan 30° = √3/3
What is the slope of the line passing through (-3, 5) and (5, -3)?
Summary:
The slope of the line passing through (-3, 5) and (5, -3) is -1
