Answer:
<h2>The answer is 2</h2>Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(82, −96) and (87, −86)
We have
We have the final answer as
<h3>2 </h3>Hope this helps you
Use formula
![\sqrt[3]{27(\cos{330^o}+i\sin{330^o})} \\\sqrt[3]{27e^{i330^o} } \\ \sqrt[3]{27} \sqrt[3]{e^{i330^o}} \\ \sqrt[3]{3^3} \sqrt[3]{e^{i110^o\times 3}} \\ \sqrt[3]{3^3} \sqrt[3]{(e^{i110^o})^ 3}} \\ 3e^{i110^o} \\3(\cos{110^o}+i\sin{110^o})](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%28%5Ccos%7B330%5Eo%7D%2Bi%5Csin%7B330%5Eo%7D%29%7D%20%0A%5C%5C%5Csqrt%5B3%5D%7B27e%5E%7Bi330%5Eo%7D%20%7D%0A%5C%5C%20%20%5Csqrt%5B3%5D%7B27%7D%20%20%5Csqrt%5B3%5D%7Be%5E%7Bi330%5Eo%7D%7D%20%0A%5C%5C%20%5Csqrt%5B3%5D%7B3%5E3%7D%20%5Csqrt%5B3%5D%7Be%5E%7Bi110%5Eo%5Ctimes%203%7D%7D%20%0A%5C%5C%20%5Csqrt%5B3%5D%7B3%5E3%7D%20%5Csqrt%5B3%5D%7B%28e%5E%7Bi110%5Eo%7D%29%5E%203%7D%7D%20%0A%5C%5C%203e%5E%7Bi110%5Eo%7D%0A%5C%5C3%28%5Ccos%7B110%5Eo%7D%2Bi%5Csin%7B110%5Eo%7D%29)
