Question

What is the equation of the given linear function?

Answer 1

Answer: A

Step-by-step explanation:

To solve this problem, think of a coordinate plane.  Look at the first x and y on the table. The x is zero and the y is 8.  Now look at the answers.  For x to be zero while y has a value would mean that it would have a y-intercept of 8. The only answer that has a y-intercept of that value is A.

To prove that A is the correct problem, try to do slope intercept with it.  The slope is 9, so the y increases by 9 and the x increases by 1.  8 + 9 is 17, which is the second y.  0 + 1 is 1, which is the second x.  So A must be the correct answer.
