Answer:
For linear equations we use:
p=mx+b ------ (1)
Now we have the following coordinates:
(x1,p1)= (1000,280) and (x2, p2)=(5000,400)
First we need slope (m)
m= 
= 
Now we will plug the value of m in the first equation

=> 
=> b = 250
Now plug into p=mx+b using only m=0.03 and b=250

When the unit price is $440, we can plug in 440 in for p;

=> 
=> 
=> x = 6333 refrigerators
The lowest price at which a refrigerator will be marketed, we can find this by plugging x = 0 in p=mx+b.

=> p = $250
Answer:
<h3>a. </h3>
Step-by-step explanation:
this my answer is perfect yap
2y-x=3/4(-y+1)first distribute
2y-x=-3/4y+3/4 get the y on one side
2y-x+3/4y=3/4 add 3/4y to both sides
2y+3/4y=3/4+x add x to both sides
11/4y=3/4+x now divide by 11/4 (both sides)
y=3/11+4/11x
y=3+4x/11
