A particular car can travel 40 miles for every gallon of fuel that it burns. Which graph best represents the relationship between the miles travelled and the gallons of fuel used? PLZ help me

This is a function

Explanation:

x = number of hours

y = amount paid

He earns $9.50 an hour, which means the equation is y = 9.50x; we multiply 9.50 by x to get the value of y.

For example, if he worked 1 hour then,

y = 9.50x = 9.50*1 = 9.50

meaning he earned $9.50 in total

If he worked 2 hours, then,

y = 9.50x = 9.50*2 = 19

is the total he earns.

The two ordered pairs found so far were (1,9.50) and (2,19). Note how each x input leads to exactly one y output. It's not possible for Dean to work some number of hours and earn two different paycheck amounts. This means we do have a function here.

In terms of a graph, plotting (1,9.50) and (2,19) shows we pass the vertical line test. We cannot draw a single vertical line through more than one point. I recommend generating more points to help further illustrate that the vertical line test is passed, and therefore we have a function.
