Step 1:
\The equation is
.
Create a word problem.
\Sammi purchased
pens and
chocolates. The total amount spent by her is
.
1) Write an equation representing the situation.
\2) Find the slope of the equation.
\3) Find the
-intercept and
-intercept of the equation.
Step 2:
\Let
be the cost of each pen.
Let
be the cost of each chocolate.
Amount spent by Sammi for pens is
.
Amount spent by Sammi for Chocolates is
.
Total amount spent by Sammi is
.
Therefore the equation is
.
The slope intercept form is
, where
is slope and
is a constant.
Convert the equation into slope-intercept form of line equation.
\
Subtract
from each side.

Apply additive inverse property
.

Divide each side by 8.
\
.
Compare the equation with slope intercept form of line equation.
\Here
and
.
Therefore, the slope of the line equation is
.
Step 3:
\Find the
-intercept by substituting
in
.
