<u>Find the slope of the perpendicular line</u>
When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.
⇒ if the slope of this line = - ¹/₂
then the slope of the perpendicular line (m) = 2
<u>Determine the equation</u>
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - (-2) = 2 (x - 0)
∴ y + 2 = 2x

There are 3 times as many earings as there are rings. Which can be written as 1/3.
Given, local sales tax rate = 7%
The selling price of car = $26,200
Now to find the sales tax for the car we have to find 7% of $26,200.
7% of 26,200 = 26200×(7/100) = (26200×7)/100 = 183400/100 = 1834
So the total sales tax paid = $1834
Now to get total cost of the car we have to add the sales tax we have got with the selling price of the car.
So, the total cost of the car = Selling price of the car + sales tax
= $26,200 + $1834
So we have got the required answers
Sales tax = $1834 and total cost of the car = $28,034
