We need to check the ordered pairs for x = -2, x=5, x= 2/3 and x = 0.75.
1. For the first function: y = 9-4x
x=-2

The ordered pair is (-2,17).
x = 5

The ordered pair is (5,-11).
x = 2/3

The ordered pair is (2/3, 19/3)
x = 0.75
Answer:
=62%
Explanation:
34/55=0.6181=0.62 rounding off to nearest 100.
34/55×100=0.62×100
=62%
It should be 80 if I’m correct
