Answer: C) 9/41
Step-by-step explanation: The ratio for cosine is adjacent/hypotenuse. 9 is the adjacent side and 41 is the hypotenuse.
The point-slope form:
We have the slope m = 3 and the point (-1, 5). Substitute:
<em>use distributive property</em>
<em>add 5 to both sides</em>
- slope-intercept form
