Answer:
Step-by-step explanation:
5.
point = (x, y)
A = ([tex]1\frac{1}{2}[/tex], 12)
B = ([tex]2\frac{1}{2}[/tex], 20)
C = (3, 24)
D = ([tex]3\frac{1}{2}[/tex], 28)
y/x ratios
[tex]\frac{12}{1\frac{1}{2} }[/tex]
[tex]\frac{20}{2\frac{1}{2} }[/tex]
24/3
[tex]\frac{28}{3\frac{1}{2} }[/tex]
6.
(1 2/3, 3 1/3) = 3 1/3 ÷ 1 2/3 = 2
(1 1/4, 2 1/2) = 2 1/2 ÷ 1 1/4 = 2
(3, 7) = 7 ÷ 3 = 2 1/3
(4 1/2, 9) = 9 ÷ 4 1/2 = 2
The ratio 7/3 (x = 3 and y = 7) is not proportionally related to the others.
The other ratios are equal to each other and are therefore in proportion.
7. yes
