Answer:
question 1: m = 3/2
question 2: m = 1/95
Step-by-step explanation:
Slope intercept form of equation is of form
y = mx+c
where m is the slope of line and c is the y intercept of the line.
Y intercept is point on y axis where the line intersects the y axis.
____________________________________
given
y = 3/2 x
comparing it with y = mx+c
we have m = 3/2 .
since y = 3/2 x does not have constant term so it can be taken as 0. hence c is 0
_________________________________________
slope for any two point (x1,y1) and (x2,y2) on coordinate plane is given by
slope = (x2-x1)/y2-y1)
From the given table lets take two point as (2,190) and(4,380)
Thus, slope m is given by
m = (4-2)/(380-190) = 2/190 = 1/95
m = 1/95
Though, slope can be taken by dividing y by x (y/x). It is good practice to use two point form formula as given above . Provided two points are given

Answer:
N = 920(1+0.03)^4t
Step-by-step explanation:
According to the given statement a car repair center services 920 cars in 2012. The number of cars serviced increases quarterly at a rate of 12% per year after 2012.
Rate is 12 % annually
rate in quarterly = 12/4= 3%
We will apply the compound interest equation:
N=P( 1+r/n)^nt
N= ending number of cars serviced.
P= the number of cars serviced in 2012,
r = interest rate
n = the number of compoundings per year
t= total number of years.
Number of compoundings for t years = n*t = 4t
Initial number of cars serviced=920
The quarterly rate of growth = n=4
r = 3%
The growth rate = 1.03
Compound period multiplied by number of years = 920(1.03)^4t
Thus N = 920(1+0.03)^4t
N = number of cars serviced after t years...
