Answer:
The correct answer is D. 1/√3
Step-by-step explanation:
The ratio of the opposite side and the adjacent side to the given angle is the tangent.
According to the image below formula is:
tangent(α)=a/b
a= oppositive side: the side in front of the given angle.
b= adjacent side: the side next to the given angle.
α= the given angle.
According to the image, the value of “a” is 1 and there is √3 for “b”.
So, the correct answer is D. 1/√3

Answer:
Step-by-step explanation:
The slope of a line is always rise over run.
To find the slope of this line, we are looking for two points that are on an integer x value and an integer y value.
One of these points is (-4, 1). Another one is (0, -2).
Studying the y-values of both (the rise), the change in y is , and since we are going down, the change is
.
Studying the x values of both (the run), we can see that the rate of change is .
So the rise over run will be , or just
. This is also the slope as slope is rise over run.
Hope this helped!
