Problem 1

<h3>The slope of the line is undefined </h3>

because this line is completely vertical. All vertical lines have undefined slopes. The x coordinates are both x = p, so there is no change in the x coordinates. Note how the slope formula below leads to a denominator of 0.

m = (y2 - y1)/(x2 - x1)

m = (-a - a)/(p - p)

m = (-2a)/0

We cannot divide by zero, which is why the slope is undefined.

=====================================

Problem 2

<h3>The equation is simply x = p</h3>

The equation of any vertical line is of the form x = k, where k can be replaced with any number or expression. In this case, we replace k with p. Let's say that p = 9. This would mean x = p updates to x = 9; telling us that we have a vertical line through 9 on the x axis.

=====================================

Problem 3

There is no y intercept if p is not equal to zero. This is because any vertical line is parallel to the y axis. Parallel lines never intersect. The y intercept is where the graph crosses the y axis.

If p = 0, then the entire line overlaps the y axis (yielding infinitely many y intercepts); otherwise, if p is nonzero, then there are no y intercepts.

<h3>The answer to part 3 will depend on the status of p being nonzero or not.</h3>

=====================================

Problem 4

<h3>Answer: 0</h3>

The original line is vertical, so any line perpendicular to this original one will be horizontal. All horizontal lines have a slope of zero.

Example: the horizontal line through (2,3) and (7,3) has a slope of zero as the slope formula below shows

m = (y2 - y1)/(x2 - x1)

m = (3-3)/(7-2)

m = 0/5

m = 0

Answer:

357.46 meters squared

Step-by-step explanation:

16 x 12.2 x 1/2 = 97.6

12.2 x 10.6 = 64.66

97.6 x 3 = 292.8

292.8 + 64.66 = 357.46
