2 answers:
Answer:
r = 
Step-by-step explanation:
Given the proportional equation
y = rx ← r is the constant of proportion
Divide both sides by x
= r
Use any ordered pair from the table.
Using (8, 2 ) , then
r =
= 
Answer:
1/4
Step-by-step explanation:
Multiplying the input (x) by (1/4) results in the output. This is direct proportion, and the constant of proportionality is (1/4).

Answer:
y=-9/2x plus 4
Step-by-step explanation:
y=ax plus b
Use points from the task.
4=0x plus b
