$8x^{-10}y^6 - 2x^2y^{-8} = \frac{8y^{14} - 2x^{12}}{x^{10}y^8}$

Step-by-step explanation:

Given

$8x^{-10}y^6 - 2x^2y^{-8}$

Required

Simplify

Rewrite as:

$8x^{-10}y^6 - 2x^2y^{-8} = \frac{8y^6}{x^{10}} - \frac{2x^2}{y^8}$

Take LCM

$8x^{-10}y^6 - 2x^2y^{-8} = \frac{8y^6*y^8 - 2x^2 * x^{10}}{x^{10}y^8}$

Apply law of indices

$8x^{-10}y^6 - 2x^2y^{-8} = \frac{8y^{14} - 2x^{12}}{x^{10}y^8}$

The equation of line of best fit is:

$y=\dfrac{15}{22}x+\dfrac{6}{11}$

Step-by-step explanation:

Clearly from the scatter plot we could observe that the line of the best fit passes through the point (8,6) and (30,21)

We know that the equation of a line, passing through two points (a,b) and (c,d) is calculated by:

$y-b=\dfrac{d-b}{c-a}\times (x-a)$

Here we have:

(a,b)=(8,6) and (c,d)=(30,21)

Hence, the equation of line of best fit is calculated as:

$y-6=\dfrac{21-6}{30-8}\times (x-8)\\\\\\y-6=\dfrac{15}{22}\times (x-8)\\\\y-6=\dfrac{15}{22}x-\dfrac{8\times 15}{22}\\\\y=\dfrac{15}{22}x-\dfrac{60}{11}+6\\\\y=\dfrac{15}{22}x+\dfrac{6}{11}$
