Answer:
y = 9.65x
Step-by-step explanation:
Given that total revenue is directly proportional to the number of units sold
Let the number of units sold be represented by x and the total revenue be represented by y
Given y∝x
y = kx where k is some constant
Also given that when 500 units are sold, the total revenue is $4825.
Here y=4825 and x=500
Now 
k=9.65
Therefore the equation representing the relation between the total revenue and the number of units sold is
y = 9.65x
Answer:
#1
x intercept is -5
y intercept is -5
#2

Answer:
-4x+4y+21
Step-by-step explanation:
-3(2x-7)+2y+2(x+y)
-6x+21+2y+2x+2y
