We are given that a car starts a journey with a full tank of gas. The equation 
relates the number of gallons of gas (y) left in the tank to the number of miles the car has traveled(x).
A. We will find y intercept by substituting x=0 in our equation,
Now let us find our x-intercept by substituting y=0 in our equation,
Therefore, x-intercept is 320 and y-intercept is 16.
B. Our x-intercept represents that after travelling 320 miles there were 0 or none gallons of gas left in tank.
C. Our y-intercept represents that there were 16 gallons of gas in car tank when car started the journey.
Answer:
x=2
Step-by-step explanation:
Here what we need is that the ratios be equal, which is:
x:(5/2) = 8:10 or, what is the same:
x/(5/2) = 8/10
Lets pick the left term x/(5/2) and multiply both numerator and denominator by 2 to eliminate the fraction on the denominator:
2x/2(5/2) = 2x/5
Now, we would like to make a 10 appear on the denominator. As we already have a five we need to multiply numerator and denominator by the num that, multiplied by 5 gives as 10, this is 2:
2(2x)/2(5) = 4x / 10
So, we transformed x/(5/2) in 4x/10, and both are the same, so we can replace it on our first equation:
4x/10 = 8/10
As both denominators are equal, we can concentrate only in numerators:
4x = 8
Dividing both sides by 4:
x = 2
So, for x=2 both ratios are equivalents.
Answer:
slope should be 1.50x and your y-intercept should be 7.50
