Answer:
Lin is correct
Step-by-step explanation:
Constant proportionality is defined as "the ratio between two directly proportional quantities"
Ratios are determined as fractions such as 1/2, 3/4, etc.
By this definition, you can tell that Lin is in the right by giving a proper constant proportionality
(-2, 0)
the y-intercept is (-2, 0), therefore that the solution.
(9/2,0) and (0,-1)
y(0) = log(1)-1 = -1
y=0 when log(2x+1) = 1
2x+1 = 10
x = 9/2
