5. •If slope is
positive or
negative,
identify 2
good points
on the line.

6. •From the lower point
count up and then
count over.
•Put in ratio
}Ratio
•Count up #
•Count over #

7. •Leave
answer in
ratio, but
reduce to
lowest
terms.

8. •Name intercepts:
•X-intercept is where the
line crosses the x axis.
(x-int)
•Y-intercept is where the
line crosses the y axis.
(y-int)
•The intercepts are only
half a point.
