The answer is Option 1: \frac{1\±i\sqrt{31}}{2}

Step-by-step explanation:

Given equation is;

x²-x+8=0

Here,

a=1 , b= -1 , c=8

Quadratic formula is;

x=\frac{-b\±\sqrt{b^2-4ac}}{2a}

Putting values in equation;

x=\frac{-(-1)\±\sqrt{(-1)^2-4(1)(8)}}{2(1)}\\\\x=\frac{1\±\sqrt{1-32}}{2}\\\\x=\frac{1\±\sqrt-31}{2}\\\\x=\frac{1\±i\sqrt{31}}{2}

The answer is Option 1: \frac{1\±i\sqrt{31}}{2}

Keywords: quadratic formula, equation

Hi there! The slope of the line is -2/5.

We can determine the slope of a line by dividing the change of y-coordinates by the change of x-coordinates.

In this situation we have a...
change of x-coordinates of (5 - 0) = 5
change of y-coordinates of (0 - 2) = -2

Therefore, the slope of this line is -2/5
