The "origin" of a line is simply the points (0, 0)
To draw a line that passes through the origin (0, 0) & has a slope of 3/5, we simply start by drawing a point at (0, 0).
Then, from there, you use the slope to find your next points.
Slope = rise/run
So, 3 is the rise, and 5 is the run.
So, starting from (0, 0), you go up 3 times, and go to the right 5 times. So, (3, 5) is your next point. Just continue doing that and you'll get a line.

Maria first made an error in step 3.
Maria can correct her error by multiplying 136.49 by 1 over 4 before subtracting 3.0625 from it.
In the b section on this piece of paper, we can see, that this would practically be a pie graph, or if you would want to call it a graph in general. As the question stated, we see how we would want to find the perimeter of the figure. So this, sense this would only be 1/4 of the figure, we would then do 4(in) x's 4 and from this, your perimeter would give you 16(in).
