You buy 8 gallons of gasoline at p dollars per gallon and pays $23.20. write an equation to find the price of one gallon of gasoline. then find the price of one gallon of gasoline.

The price of one gallon is $2.90

Step-by-step explanation:

The equation to calculate the price of one gallon could be calculated by multiplying the 8 gallons and the price of one gallon of gasoline (p), this is:

So clearing the value of p, we have:

Finally, the price of one gallon is $2.90

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
