Answer:
Hoping someone else can answer with more confidence, but here's what I have:
on the left hand side:
upper is partial/penumbral lunar eclipse
lower is total solar eclipse
on the right hand side:
on the top: it's impossible for the moon to be behind the sun, so I'm not sure what they want there
middle is total solar eclipse
bottom is partial/penumbral lunar eclipse
Hope I helped at least a little

Y= 2x-1
Explanation: First, you find slope. If the first point it x-axis point is 0 and the second x-axis point is 1 then you already know the answer is over 1, so you have to figure out how many up you are going on the y-axis from -1 to 1. Which is 2, so your slope is 2/1 or just 2. Next, you find your y-intercept, which is where the line crosses the y-axis, and the easy way to find this is finding what y is equal to when x is equal to 0, in the problem you are told (0, -1) as a point, so they gave you your y-intercept right there, which is -1. Finally you right the equation in slip intercept form (y= mx+b) which is y= 2x-1
80%, 1000-200 = 800/1000 or 80%
