The slope of the line is 2/3.
What is a line?
A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it. Collinear points are two points that are located on the same line.
Given coordinates of the points are A(1,-9) and (4,-7).
The formula of slope of a line that passes through the points (x₁, y₁) and (x₂, y₂) is (y₂ - y₁)/(x₂ - x₁).
Here x₁ = 1, y₁ = -9, x₂ = 4, and y₂ = -7
m = (-7 - (-9))/(4 - 1)
m = 2/3
