Question 401564: i have a graph,the following graph shows the depriciation for a corprate airplane from 2006 to 2009. the plane was purchases new in 2006;therefore,x=0 represents the year 2006. x-axis(horizontal)= years starting from 0=2006 and increasing by 0.5 years Y-axis(vertical)= price in $ amounts
A) list the coordinates of two points on the graph in (x,y) form?
(1.0__,_228000____), (__3.0,_204000___)
B) Find the slope(rate of depriciation) of this Line
C)Find the equation of this line in slope-intercept form..

You can put this solution on YOUR website! A) list the coordinates of two points on the graph in (x,y) form?
(1.0__,_228000____), (__3.0,_204000___)
---------------------------------------------
B) Find the slope(rate of depriciation) of this Line
slope = (208000-204000)/(3-1) = 4000/3
----------------------
Find the equation of this line in slope-intercept form..
Form: y = mx + b
Substitute to solve for "b":
228000 = (4000/3)(1) + b
b = 22666.67
---------------
Equation:
y = (2000/3)x+22666.67
===============================
