<u>Answer:</u>
Slope = 6
<u>Step-by-step explanation:</u>
Taking two points on line l to find its slope: (0, 3) and (6, 2).
Slope of line l = ![\frac{3-2}{0-6} =-\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B3-2%7D%7B0-6%7D%20%3D-%5Cfrac%7B1%7D%7B6%7D)
We know that the slope of a line which is perpendicular to another line has a slope which is a negative reciprocal of the other line.
Therefore, the slope of the line which is perpendicular to line l will have a slope of 6.

Step-by-step explanation:
Total teens = 28
12 teenagers, in total, had a sister
7 teenagers, in total, had a brother
3 teenagers had both a sister and brother.
To get the required probability, we will consider the following two details:
3 teenagers have both a brother and sister and 12 have a sister.
Therefore, the probability that a randomly selected teenager who has a sister also has a brother will be = ![\frac{3}{12}=\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B12%7D%3D%5Cfrac%7B1%7D%7B4%7D)
