A line passes through the points (P, a) and (P, –a) where P and A are real numbers and P does not equal 0. Describe each of the following. Explain your reasoning. 1. slope of the line

2. equation of the line

3. y-intercept

4. slope of a line perpendicular to the given line

9514 1404 393

Step-by-step explanation:

2. The x-value of the given points is the same, so the points both lie on the vertical line ...

  x = P

__

1. The slope of a vertical line is "undefined".

__

3. Given that P ≠ 0, the vertical line is parallel to the y-axis, so there is no y-intercept.

__

4. A line perpendicular to a vertical line will be horizontal. A horizontal line has a slope equal to zero.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
