To find the depreciation of the car take the amount it goes down by each year (4.1%) and make x the number of years. 34000 · (4.1% · 7) = 9758. That's your depreciation. Now just subtract the depreciation from the total and you get 24242
Answer: y=x
The slope of the perpendicular line is the opposite reciprocal. So you do -(-1/1) which equals 1. So now we have y=x+b. Plug (3,3) into this and you get 3=3+b. So b=0 and the equation is y=x
Answer:
Equation of the perpendicular line is 
Step-by-step explanation:
Given equation is y = 5x - 4
By comparing this equation with slope-intercept form of the equation,
y = mx + b
Slope of this line 
Let the slope of the perpendicular line = 
By the property of perpendicular lines,



Equation of the perpendicular line passing through a point
and slope m is represented by

If the given point is (10, -1) and slope 'm'= 



The slope of the line would be 4/5 because it is going up 4 units (positive) and going to the right (positive) 5 units
