Choose the correct slope of the line that passes through the points (1, −3) and (3, −5).
The slope of a line determines the inclination of the line with the positive x-axis.
Answer: The slope(m) of the line that passes through the points (1, −3) and (3, −5) is m = -1.
Let us find the slope of a line when two points on the line are given.
The slope of the line passing through (x1, y1) and (x2, y2) is given by m = (y2 - y1) / (x2 - x1)
Here, (x1, y1) = (1, −3) and (x2, y2) = (3, −5)
m = (y2 - y1) / (x2 - x1)
m = [-5 - (-3)] / [3 - 1]
m = [-5 + 3] / 
m = [-2] / 2
m = -1
Slope = m = -1
