Question 1077449: By reading a graph on defense spending in the country of Warpeas, you discover that in year 0 the country spent $176 million on defense and in year 8 spent $528 million. Write a linear function that relates y (in millions of dollars) to x. Answer by srinivas.g(540) (Show Source):
You can put this solution on YOUR website! y represents the money spent on defence
x represents time
y is a linear function of x
hence y= ax+b, where a, b are constants
for x=0, y= $ 176 million
put these values in the above equation
176 = a(0)+b
176 =b
hence b= 176
for x= 8, y= 528 million
hence 528 = 8(a) +b
but b=176
hence 528 = 8*a+176
{{[ 352=8a}}}
hence a= 44 and b =176
Hence y= 44x+176
