Answer:
8 ft², 21.8ft², and 11.2ft²
Step-by-step explanation:
7/9 = 42/54...when 42/54 reduces, it becomes 7/9...so this is proportional because proportions are nothing but equivalent fractions.
u could also check it this way...
12/21 = 15/24
cross multiply
(21)(15) = (12)(24)
315 = 288.....these do not equal and are therefore, not proportionate
440/4 = 300/3
110 = 100....not equal, so not proportionate
120/5 = 88/4
24 = 22.....not proportionate
66/82 = 99/123
0.804 = 0.804.......these are proportional
68/172 = 43/123
0.395 = 0.349......nope, not proportional

Answer: -2/3</h3>
==========================================
Work Shown:
Use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (-3 - 5)/(5 - (-7))
m = (-3 - 5)/(5 + 7)
m = (-8)/(12)
m = -2/3
