Answer:
y = - x - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 5, 4) and (x₂, y₂ ) = (5, - 8)
m = = = -
y = - x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (5, - 8), then
- 8 = - 6 + c ⇒ c = - 8 + 6 = - 2
y = - x - 2 ← is the equation of the line
Part A:
Given that <span>a dinette table with a cash price of $200 is purchased at $8.50 down and $11.00 per month for 24 months
The total installment price is given by
Part B:
The carrying charges is given by the total installation price minus the cash price.
From part a, we obtained that the total installation price is $272.50 and given that the cash price is $200.
Therefore, the carrying charges is given by
$272.50 - $200.00 = $72.00
Part C:
If the money is to be saved at $11 per month to be able to purchase the table at the cash price, the number of months it will take to be able to save $200 at $11 per month is given by
Therefore, it will take 19 months </span><span>to save the money at the monthly rate needed to buy the item for its cash price.</span>
This is the correct answer is X=0 and y= 4.
