Having
trouble with Green Globs?
Remember, we
will be having a tournament to see who is the best at Green Globs. You will be
receiving a grade based on how well you do in the tournament so do your best.
Lines
You will
basically be using four types of lines:
Horizontal (y=)
Vertical (x=)
Uphill (y=mx+b,
positive slope)
Downhill
(y=mx+b, negative slope)
Figuring out your slope (m)
- Look at the line to determine if the
slope is positive or negative
- Find two points that fall on the
line
- count the “change in y” (rise)
between the two points
- count the “change in x” (run) using
the same two points as above
- put you two numbers in fractional
form
(“change in y” over “change in x”)
- reduce the fraction and put it in
for “m” in y=mx+b
Figuring out your Y-intercept (b)
1.
Find the
point where the line crosses the y- axis, this is your y-intercept.
- Put this number in for “b” in y=mx+b, remember to change the sign
accordingly
Graphing with Green
Globs
q
The goal is to hit as many globs
as you can with each shot. The more you hit, the higher your score.
q
The amount
of points you get is based on the following:
1
glob =1 point
2
globs = 1 + 2 points
3
globs = 1 + 2 + 4 points
4
globs = 1 +2 + 4 + 8 points and so on…
q
Look for a
group of globs that are aligned nicely, this will allow you to hit as many as
possible with one shot.
q
Calculate
your slope and y-intercept.
q
Plug them
into y=mx+b and fire away.
q
Remember,
if you are unhappy with the shot, “undo” it and try again.
