A line parallel to the y-axis that passes through (77,88) is x = 77. There is no slope-intercept form of this equation if our coordinate system is based upon a horizontal x-axis and a vertical y-axis.
Answer:
Well if (a,b) is in Quadrant IV which is the last quadrant the a or x is a positive number and the b or y is a negative number.
Where because I do not see it
To solve this problem you must apply the proccedure shown below:
1. You have that the ratio of the tangent function is:
tan(angle)=opposite/adjacent
2. Keeping this on mind, you have:
tan(A)=12/5
Therefore, the answer is:
tan(A)=12/5
