The following statements are true and correct:
____________________________________________________
[A]: y is a function of x .
____________________________________________________
[B]: The graph of the relationship is a line.
____________________________________________________
[D]: When the input is -2, the output is 3.

Choice: [C]: "When the input is -3, the output is 4 ." → is INCORRECT.
Note: When the input is -3, the output is "4 <span>⅓";
that is, when x = -3, y = 4 </span>⅓ .
_____________________________________________________
Choice: [E]: "The y-intercept of the relationship is: (0,1)." → is incorrect.
Note: The y-intercept refers to the value of "y" where the line crosses the "x" axis. From the equation; and form the graph, we see that the y-intercept is: "⅓" ; or, "(0, ⅓)" .

Answer:
each of the 12 turns is 150°
Step-by-step explanation:
If we number the points of the star 1–12, in order for the star to be symmetrical, each point must connect to two points symmetrically located around the centerline.
That is, point 1 may connect to points {2, 12} or {3, 11} or {4, 10}, or {5, 9} or {6, 8} or {7, 7}. For each of these connections, the angle made at the point of the "star" is, respectively, 150°, 120°, 90°, 60°, 30° or 0°. For these angles, the figure obtained will be ...
150° - dodecagon, a 12-sided figure
120° - hexagon
90° - square
60° - equilateral triangle
30° - 12-pointed star
0° - straight line
The two 12-pointed figures are shown in the attachment.

We suspect the star you're interested in is the one with points that are 30°. In order to have that point angle, the spider must make a turn of 180° -30° = 150°.
The spider will make 12 turns of 150°, for a total of 1800°, for a total of 5 full turns of 360°.
