Anyone not so busy? i need help with 9th grade maths

The line containing the midpoints of the legs of right triangle abc where a(-5,5), b(1, 1), and c(3, 4) are the vertices.

What is the equation of the line in point-slope form? y+ 4 = 1/2(x+4) y-4 = 1/2(x + 4) y-0 = 2(x - 4) y-4 = 2(8-0)

Complete the input-output table for the linear function y = 3x. complete the input-output table for the linear function y = 3x. a = b = c =
