To find the median, we must order the numbers.

12,12,13,13,14,15,16,17,18,19

Now see which one is in the middle.

We are stuck between 14 and 15, so what is between those?
14.5 is between 14 and 15, so that is the median.

Answer: 14.5 is the median

Write the equation of the line that passes through (2, 3) and is parallel to the line 12x – 5y = 2.

vladimir1956 [14]

$k:12x-5y=2\to-5y=-12x+2\ \ \ /:(-5)\to y=\frac{12}{5}y-\frac{2}{5}\\\\l:y=mx+b\\\\k\ ||\ l\iff m=\frac{12}{5}\\\\ l:y=\frac{12}{5}x+b;\ (2;\ 3)\\\\\frac{12}{5}\cdot2+b=3\\\\\frac{24}{5}+b=3\\\\b=\frac{15}{5}-\frac{24}{5}\\\\b=-\frac{9}{5}\\\\Answer:y=\frac{12}{5}x-\frac{9}{5}\to\frac{12}{5}x-y=\frac{9}{5}\ \ \ \ /\cdot5\to12x-5y=9$
