ANSWER
The linear equation is: y = 80x + 65
Te cost for 40 football jerseys: $3265
EXPLANATION
Let 'x' be the number of jerseys and 'y' the cost of x jerseys.
Each jersey costs $80, so the cost of x jerseys is 80x. There's also an extra fee for procesing of $65, which is the same no matter how many jerseys they buy.
Therefore, the cost 'y' of x jerseys is:

Now we want to know the cost of 40 football jerseys, so we just have to replace x by 40 and solve:
Answer: The required product is 
Step-by-step explanation: We are to find the product f the following two algebraic expressions:

To find the product of the above two expressions, we must multiply each term of the first expression with each term of the second expression.
The multiplication is as follows:

Thus, the required product is

Answer:
y = 3x - 1
The slope intercept is -1.
To find the slope, do the formula (y sub2 minus y sub1)/(x sub2 minus x sub1) then reduce.
(14 - (-10))(5 - (-3)) = 24/8
24/8 = 3
