Scott is putting money into a checking account. let y represent the total amount of money in the account (in dollars). let x represent the number of weeks scott has been adding money. suppose that x and y are related by the equation y = 50x + 450 .

Part 1) The change per week in the amount of money  is  $50

Part 2) The starting amount in the account is $450

Step-by-step explanation:

The complete question is

Scott is putting money into a checking account. Let y represent the total amount of money in the account (in dollars). Let x represent the number of weeks Scott has been adding money. Suppose that x and y are related by the equation y = 50x + 450.

Note that a change can be an increase or a decrease. For an increase, use a positive number. For a decrease use a negative number.  

1. WHAT IS THE CHANGE PER WEEK IN THE AMOUNT OF MONEY IN THE ACCOUNT?  

2. WHAT WAS THE STARTING AMOUNT OF IN THE ACCOUNT?

Let

x ------> the number of weeks Scott has been adding money

y ------>  the total amount of money in the account (in dollars)

we have

This is the equation of a line in slope intercept form

where

The slope m is

The y-intercept b is

therefore

The change per week in the amount of money  in the account is equal to the slope of the linear equation, so is equal to

The starting amount in the account is equal to the y-intercept of the linear equation ( value of y when the value of x is zero), so is equal to

we don't have enough info to solve this

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
