1. Identify each of the following situations or equations as proportional or non-proportional and explain your reasoning.
(a) The total cost of rent is determined by recording x months of rent at $1400 per month, plus a $150
application fee.
(b)

(c) y
(d) y =
X-6

A: Is proportional because if you plug it in a graph the equation would be y=1400x+150
Where y is the total of rent x is the unknown amount of months 1400 is how much it is a month and the 150 is the
extra fee.
