HELP ME PLEASE!!!

ser-zykov [4K]

parallel lines, have the same exact slope, hmmm what is the slope of y = -2/3 x + 1/3 anyway? well, low and behold, the equation is already in slope-intercept form, therefore

$\bf ~~y=\stackrel{slope}{-\cfrac{2}{3}}x+\cfrac{1}{3}~~$ has a slope of -2/3.

so we're really looking for a line whose slope is -2/3 and runs through 9,4.

$\bf (\stackrel{x_1}{9}~,~\stackrel{y_1}{4})~\hspace{10em}slope = m\implies -\cfrac{2}{3}\\\\\\\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-4=-\cfrac{2}{3}(x-9)\\\\\\y-4=-\cfrac{2}{3}x+6\implies y=-\cfrac{2}{3}x+10$

$\large \rm \frac{2 ^{3} }{ \sqrt[4]{2} }$

$\large \rm \frac{2 ^{3} }{2 ^{ \frac{1}{4} } }$

Divide the terms with the same base by subtracting their exponents

$\large \rm \: 2 ^{3 - \frac{1}{4} }$

Calculate the difference

$\large \rm2 ^{ \frac{11}{4} }$
