SLOPE CALCULATION
The formula to calculate the slope of a line is given to be:
The points on the line are labeled as shown below:
The coordinates of the points are given to be:
Therefore, the slope can be calculated to be:
Therefore, the slope is calculated to be -1.
DESCRIPTION OF THE SLOPE
Slopes come in 4 different types: negative, positive, zero, and undefined.
The slope calculated is a NEGATIVE SLOPE.
