Answer:
Option c
Step-by-step explanation:
We assume that the angle is in the first quadrant.
Observe the attached image.
if 
So:

By definition:

So:
adjacent side = 3
hypotenuse = 5.
Observe the attached image
We find the opposite side "x" using the Pythagorean theorem.

Then, for the angle u:

If I am sure the answer is D
I am thinking A) Or B) because iPlease chose as best if i am wrong please don't be mad most of my stuff is correct
Answer:
y = 2x + b (the second answer choice)
Step-by-step explanation:
The slope-intercept form is y = mx + b (the m representing slope and the b representing y-intercept). Put the points in ratio form as a fraction and subtract the ratio with the smallest numbers from the ratio with the largest ratio (5/1 - 1/-1) to get 4/2. When simplified, it becomes 2/1, so the slope is 2. Using the slope found previously, subtract 1 from the x of (1, 5) and 2 from the y of (1, 5) to get the y-intercept. The resulting point is (0, 3), so the y-intercept is 3. Replace the m with the found slope (2) and b with the found y-intercept (3) to end up with y = 2x + 3.
