Answer:
A
Step-by-step explanation:
First, find the y-intercept by seeing where the line goes through the y-axis
This is at (0, -2) so the y-intercept is -2.
Then, use rise over run to find the slope.
The slope is -3
im not sure about the first one but im 100% about 2 and 3
2-A
3-D
Answer:
Step-by-step explanation:
This is classic right triangle trig. First decide how each side is related to the angle theta. The side 7.7 is opposite the angle theta, while the side 14 is adjacent. That is the tangent ratio by definition. Setting up the tan ratio:

To find a missing angle on your calculator, hit the 2nd button, then the tan button and enter in 7.7/14 and hit enter. You should get an angle measure of 28.8°
If you did not get 28.8 then you are probably in radians. Check it in the "mode" of your calculator.
