Let’s also do some basic math and
algebra review.

In another area we need to review the “constructs”
of “rectilinear
graphs”

![Page 24: Unit 3: Earth the Planet of Life – the 4 “Spheres” “Dry-Lab” L-1023 Earth over Time](https://reader035.vdocument.in/reader035/viewer/2022062500/568157f3550346895dc5704e/html5/thumbnails/24.jpg)
For a rectilinear graph or a coordinate graph we
need a pair of axis.
Can you name the horizontal
axis?

![Page 25: Unit 3: Earth the Planet of Life – the 4 “Spheres” “Dry-Lab” L-1023 Earth over Time](https://reader035.vdocument.in/reader035/viewer/2022062500/568157f3550346895dc5704e/html5/thumbnails/25.jpg)
The horizontal
axis is called the “X” axis.

X
![Page 26: Unit 3: Earth the Planet of Life – the 4 “Spheres” “Dry-Lab” L-1023 Earth over Time](https://reader035.vdocument.in/reader035/viewer/2022062500/568157f3550346895dc5704e/html5/thumbnails/26.jpg)
For a rectilinear graph - can you name
the vertical axis?
U3: The 4 “Spheres”L1023 – ACT (Data

![Page 27: Unit 3: Earth the Planet of Life – the 4 “Spheres” “Dry-Lab” L-1023 Earth over Time](https://reader035.vdocument.in/reader035/viewer/2022062500/568157f3550346895dc5704e/html5/thumbnails/27.jpg)
The vertical axis – is
called the “Y” axis.

Y
![Page 28: Unit 3: Earth the Planet of Life – the 4 “Spheres” “Dry-Lab” L-1023 Earth over Time](https://reader035.vdocument.in/reader035/viewer/2022062500/568157f3550346895dc5704e/html5/thumbnails/28.jpg)
When someone wishes to
plot a “data point” on a rectilinear graph –or- coordinate
graph…
… it is done with
“coordinates”
U3: The 4 “Spheres”L1023 – ACT (Data

Y
![Page 29: Unit 3: Earth the Planet of Life – the 4 “Spheres” “Dry-Lab” L-1023 Earth over Time](https://reader035.vdocument.in/reader035/viewer/2022062500/568157f3550346895dc5704e/html5/thumbnails/29.jpg)
The “coordinates
” tell us where to put
the data point. This
type of graph
usually has at least TWO variables for
each data point.

Y
![Page 30: Unit 3: Earth the Planet of Life – the 4 “Spheres” “Dry-Lab” L-1023 Earth over Time](https://reader035.vdocument.in/reader035/viewer/2022062500/568157f3550346895dc5704e/html5/thumbnails/30.jpg)
Either the values for “X”
are “dependent”
variables making “Y”
values “Independent” variables…, or it can be
just the opposite – the
scientist decides.

Therefore; if “Y” is
changing (dependent
variable) because of
what you are specifically doing as a scientist in the study
(independent variable);

Another way to say this is:
“Y” (dependent variable) is the “effect” while X”
(independent variable) is
the “cause”

Yes, the two combined gases DID decrease. As they went from 90% -to- 55%
Yes, it was the CO2(g) decreased from 80% to 20%
