Answer:

Step-by-step explanation:

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(-2,\:-3\right),\:\\\left(x_2,\:y_2\right)=\left(8,\:-3\right)\\\\m=\frac{-3-\left(-3\right)}{8-\left(-2\right)}\\\\m=0$

It is Zero because there is no change on the y axis

If it was no change on the x it would be undefined because you can’t divide by zero

so it should be zero

Answer:

±6i√2

Step-by-step explanation:

Recall that the square root of a negative number is imaginary, which is shown by the use of "i."

Examples: √4 = ±2; √4 = i√4 = ±i2

Then √72 = ±√36√2 = ±6√2, and

√(-72) = ± i√36√2 = ±6i√2

Note that this is identical to the result shown in the problem: √(36·2·(-1) )
