Determining the Slope of a Line

Determining the Slope of a Line 1.1 - Solution

arrow_back Return to Determining the Slope of a Line
a
In order to determine the slope of the line that passes through the given points, we will use the slope formula. In the formula, represents the slope, and and represent points that lie on the line. We will start with the following points. Let's substitute these points into the formula.
In this case, we have a positive slope and it is
b
Next, we will use the points and to find the slope.
Since the formula gave us and we cannot divide a number by , it is an undefined slope.
c
The third set of points is the following. Let's substitute them into the formula.
The slope of the line that passes through the given points is negative and it is
d
In this part, the following points are given. We will substitute them into the formula, as we did in the previous parts.
Since the slope is it is a negative slope.
e
Our last set of points is given below. Let's use these points in order to determine the slope of the last line.
As a result, we have a zero slope because our slope is
