35. Solve the following system of equations graphically. State the coordinates of all points in the solution.
x + y = 5
Note that arrows at the ends of the lines were not required. Labeling the lines wasn't required. I'm assuming because it was a Geometry test and not an Algebra test. I still recommend you do these things anyway, in case the standards change again.
Two points for x and y, with work. Three points if you got as far as 18 and 34, or if you came up with 52 (without solving 18 and 34 separately). With all those calculations, many students lost a point for a computation error, such as -1 + 15 = 16.
37. Point P is 5 units from line j. Sketch the locus of points that are 3 units from line j and also sketch the locus of points that are 8 units from P. Label with an X all points that satisfy both conditions.
Note that it didn't have to look pretty. In a "sketch", you don't need to measure with a ruler or draw a circle with a compass. (Neither of which I had on hand, obviously.)
Part 4 was worth 6 credits. Please don't ask me individual questions about your proof. This is A proof. Yours might've looked similar or not. It might've had more statements. It might have skipped a statement. As long as the important stuff is there, you did okay. Looking at the sample proofs given, this one would have received full credit.
There are many possible variations, which is why I try not to grade the proofs if I don't have to. I would go insane applying Regents rubrics/grades to them.
How'd everyone do?
