Question

Which of the statements about the graph is true? :((

Answer 1

Your answer is D.

Explanation:

It is a straight line also known as proportional. The first impression, A appears to be accurate, but closer inspection reveals that the graph's slope is actually 2x. 18 (x = 0/y intercept) and ends at x = 1, where little y is at 16. Any time x expands by one, the y value falls by two. This says that the graph's equation is -2x + 18 = y.

Answer 2

Answer: D / none are true

Since it's proportional (it's a straight line), B and C are automatically wrong. A would seem true at first glance, BUT if you look closely at the graph, the slope of the graph is actually 2x.

Look at the beginning of the line. It starts at 18 (x = 0/y intercept) and at x = 1, you can see that y is at 16. The y value goes down by 2 every time x increases by 1. This means that the equation of the graph is -2x + 18 = y.

The graph is proportional and has an equation of y = -2x + 18. This means that A, B and C are incorrect.
