Answer:
On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.
Step-by-step explanation:
This function is linear, which means that it increases at a steady rate and has the following form:

Where "a" is the slope or the rate at which "y" changes for every change in "x". While "b" is the number at which the function crosses the "y" axis.
On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.
Answer:
The price of each meal cost before tax is $ 6.367
Step-by-step explanation:
Given as :
The total price of three meals = $ 20.25
The sales tax included in the total price = 6 %
So, Let the cost of meal before sales tax = x
Or, x + 6 % of x = $ 20.25
or, x + 0.06 x = $ 20.25
Or, 1.06 x = $ 20.25
∴ x = 
I.e x = $ 19.10
Or, price of three meals before tax = $ 19.10
so, The price of each meal =
= $ 6.367
Hence The price of each meal cost before tax is $ 6.367 answer
4x/4= x
4y/4 = y
8/4=2
Answer: y=2
All I know is that you should multiply than add all of the products
