In order to check proportionality, we need to check it's divisibility for two instances,
First = 35 - 30 /1 = 5/1 = 5
second = 30 - 25 / 2-1 = 5/1 = 5
As, slope (m), is constant for every step, the relation is proportional

You can analyze it in this way:
1)(2) in y2-2y can show that was (y-1)^2 so we add -1 to -8 => -9
2)(8) in x2-8x show us that was (x-4)^2 so we add -16 to -9 => -25
and finally we have:(x-4)^2 + (y-1)^2 =25
it means C is true!
Find his rate:
120 / 15 = $8 per hour
Multiply the rate by hours:
$8 x 20 hours = $160
He will earn $160
Answer: y - 3 = -1/5(x+5)
Step-by-step explanation:
