Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.
The values have being matched to the variables that they represent here:
- x-variable: the number of hours Sam works at the airport
- y variable: the amount in dollars that Sam has after paying back Daniel
- 12: amount in dollars that Sam earns per hour.
- 40: the amount in dollars Sam owes Daniel
<h3>How to solve for the equation.</h3>
The equation of this form y = 12x-40
The variable y has been said to be the amount sam has after Daniel has been paid.
X is the amount that has to be multiplied by what he earns in dollars by the hour.
40 dollars is the amount that he owes which is going to be subtracted from what he earns by the hour.
