$C(44,21)=\dfrac{44!}{21!23!}=\dfrac{24\cdot25\cdot\ldots\cdot43\cdot44}{2\cdot3\cdot\ldots\cdot 20\cdot21}=2,012,616,400,080\\
\approx2.013\cdot10^{12}$

Find the equation that Passes through the point (2,3) and is parallel to the line y=5x-9. First find the equation of the line in

KATRIN_1 [288]

Since It's parallel to y=5x-9 the slope of this new line is 5
so the equation looks like y=5x+b
to find be we just replace x by 2 and y by 3
3=10-b so b = -7
the equation is y=5x-7
