We are given a line segment in which the endpoint has coordinates (-3,1), and we are asked to find the tangent of the angle form by this line segment. If we graph the line segment we can see the following:
We have a triangle which an opposite side of 1 and an adjacent side of -3, and the definition of the tangent is the following:
[tex]\tan x=\frac{opposite\text{ }}{adjacent}\text{ }[/tex]Therefore, if we replace the values, we get;
[tex]\tan x=\frac{1}{-3}[/tex]therefore, the value of the tangent is -1/3 and not 3. The answer is:
Jenna is incorrect because the correct value of tan is -1/3
