These two lines cannot be perpendicular. For one line to be perpendicular to the second one, their gradients are related by the following:
Gradient of line 1 = -(1/gradient of line two)
In the current case, gradient of line 1=2 and gradient of line two = 1/2. If gradient of line two was = - 1/2, then they would be perpendicular.
See the graph in the attached image.
The answer is fx and the total is gs[x]
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
I am unable to read all of the options in the picture you provided but I hope this helps! (:

12 + -6i = 0
Solving
12 + -6i = 0
Solving for variable 'i'.
Move all terms containing i to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + -6i = 0 + -12
Combine like terms: 12 + -12 = 0
0 + -6i = 0 + -12
-6i = 0 + -12
Combine like terms: 0 + -12 = -12
-6i = -12
Divide each side by '-6'.
i = 2
Simplifying
i = 2</span>
