7-3+8-2-6+) i need solving this math problem

What are the coordinates of the point is 1/4 of the way from a (-6, -3) to b (6, 1)? a. (-3, -2) b. (0, -2) c. (-1, 0) d. (3, 2)

If 3x+8=3x+8 is it one solution or no solution

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.
