Answer:
A
Step-by-step explanation:
A shift along the x-axis is the opposite in the graph than in the equation. Rather than the x-intercept(s) being negative if the equation is x - n, they become positive; likewise for the other way around. A is the only answer that follows this rule. However, the y-intercept is y = n, so if n is negative, y gets shifted down rather than up.

Start off by finding the slope of the line with the formula

Answer: sen = -15; cos= 8
cot is the cotangent which is calculated by dividing cos by sen. So the dominator(15) is sen and the other number is the cos.
Notice that the number is negative which means one of them (sen or cos) is negative. We know that the angule is in the forth quadrant, and that tells us that, in that quadrant, x is a positive number while y is negative.
X is the cos function and Y is the sen. So, if y is negative, so is sen.
