CPM Homework Help : GC Problem 1-36

The slope of a line is a measure of its steepness and indicates whether it goes up or down from left to right. For example, the slope of the line segment $A$ at right is $\frac{1}{2}$ , while the slope of the line segment $B$ is $-\frac{3}{4}$ .

Line segment A: diagonally up 2 and right 4. Line segment B: diagonally down 3 and right 4.

For each line segment below, find the slope. You may want to copy each line segment on graph paper in order to draw slope triangles.

Hint:

Create a slope triangle for each segment.

Find the change in $y$ and the change in $x$ for each segment.
See the example below. Note: $Δ =$ change.

Vertical & horizontal segments form a right angle, vertical segment labeled, delta y = negative 3, horizontal segment labeled, delta x = 5.

Answer (a):
$\frac{\Delta y}{\Delta x}=-\frac{3}{5}$

Answer (d):
$\frac{\Delta y}{\Delta x}=-\frac{0}{7}=0$
