The slope is 40 and the y-intercept is 30.
Umm... What exactly are you asking for? I'm a bit confused about this question.
Divide it by 4/4. You should get 7/8. 7/8 is the same as 28/32. 28/4=7, 32/4=8. Therefore, you can divide it by 4/4.
The 90° CCW transformation is
... (x, y) ⇒ (-y, x)
For your point, this is ...
... (-3, -4) ⇒ (-(-4), -3) = (4, -3)
