1) Help please! Can someone find the slope of the line above ^^^ with the coordinates (-2, -3) and (3, 7).

2) Now for the hexagon problem:: A regular hexagon has rotational symmetry about its center. What is the minimum number of degrees of rotation necessary to show rotational symmetry? Explain your reasoning using math vocabulary.

3) Write in a simpler, shorter form without parentheses! SIMPLIFY!:

-2(3x-5)+2x-2(5-x)

Thank you!
