# How do you graph the number 7 - 5i in the complex plane and find its absolute value?

I found a value of $8.6$
On the complex plane you use the horizontal axis to plot the number of the real part ($7$) and the vertical one for the imaginary ($- 5$):
The absolute value, I think, would be the modulus of your number, i.e., the distance $\rho$ from the origin to the point representative of your number that we can find using Pythagoras:
$\rho = \sqrt{{7}^{2} + {\left(- 5\right)}^{2}} = \sqrt{49 + 25} = 8.6$
