Answer:
It is -4 :)
Step-by-step explanation:
I just did this lol
Equation of the line:
y=mx+b
Ordinate at the origin (where the line cut the y-axis): b=1
B=(-5,5)=(xb,yb)→xb=-5, yb=5
C=(0,1)=(xc,yc)→xc=0, yc=1
m=(yc-yb)/(xc-xb)
m=(1-5)/(0-(-5))
m=(-4)/(0+5)
m=(-4)/(5)
m=-(4/5)
y=mx+b
y=-(4/5)x+1
Multiplying the equation by 5:
5[y=-(4/5)x+1]
5y=-4x+5
Adding 4x both sides of the equation:
5y+4x=-4x+5+4x
4x+5y=5
Answer: The equation for BC is: Third option 4x+5y=5

Create an equation from the word problem and solve.
Answer:
$1.25 per cup
Step-by-step explanation:
To work this out you would simply divide the price of $5 by the quantity of 4, which gives you 1.25. This is because the price of 4 has been given, and so to find the price of one you would divide the price by the quantity.
The price per unit is 
1) Divide 5 by 4.

Double checking:
To double check your answer you would multiply 1.25 by 4. And if the answer is 5 then you know that your price per unit is correct.
1) Multiply 1.25 by 4.
