What is the equation in point-slope form of a line that passes through the points (-4, -1) and (5, 7)? Y-1=8/9(x-4)
Y+1=8/7(x+4)
Y+4=9/8(x+1)
Y+1=8/9(x+4)

I'm terrible at math any here is appreciated.

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

After applying the composition r0.90 ry to rs what are the coordinates of r' and s'? a.r'(–3, 1),  s'(–3, 5)b.r'(–1, 3),  s'(–5, 3)c.r'(1, 3),  s'(5, 3)d.r'(5, 3),  s'(1, 3)
