Answer:
Y = -1/2x + 7/2
Step-by-step explanation:
slope = -1/2

square root of negative is an imaginary solution or number. meaning it exist somewhere. square root of 64 is 8 and the square root of 25 is 5. "i" represent imaginary number
-vp + 30 < 45....for v
-vp < 45 - 30
-vp < 15
-v < 15/p
v > -15/p <==
============
3w - 6r = 30 ...for r
-6r = 30 - 3w
r = (30 - 3w) / -6
r = -5 + 1/2w...or r = 1/2w - 5 <==
