Question

(05.03 MC)A graph is shown below:

What is the equation of the line in slope-intercept form?

Answer 1

Answer: C

Explanation:

Looking at the graph, we can see that the y-intercept is 16. Know this, we can automatically eliminate A, B, and D. To be sure, we should also check to make sure C is our right answer.

To find the slope, we cna take any 2 points and fill in the equation
`m=(y_(2)-y_(1) )/(x_(2)-x_(1) )`. Let's use (8,0) and (6,4).

`m=(4-0)/(6-8) =(4)/(-2) =-2`

In answer choice C, the slope is -2. Therefore, C is the correct answer.
