2-41.
Without graphing, calculate the slope of each line described below.
A line that goes through the points
and . Use a slope triangle or another method to determine the slope of the line.
Another method is to first subtract the
-values and the -values from each other.
Substitute the differences into the slope formula.
A line that goes through the origin and the point
. See part (a).
A vertical line (one that is “up and down”) that goes through the point
. Vertical lines have an undefined slope.
A line that goes through the points
and . See part (a).
