My teacher doesnt tell us how to do any thing and i dont know how to do this problem: which graph best represents the solution set of y + 2 ≤ 3/2x

Which function is shown in the graph below?

If the measure of xyz is 81 what is the measure of yz

65 8 7 4 5 6 8 4 3 2 1 9 5 6 4 2 1 6 5 1 5 1 3 2 3 5 multiply the third number in the first row by the seventh number in the third row. add this result to the fifth number in the second row. add to this total ten times the fourth number in the third row. subtract the eighth number in the first row from the result.
