Answer:
(-3, 3√3)
Step-by-step explanation:
Evaluate each of the coordinates. Keep or drop the "i" as your convention requires.
6(cos(120°), i·sin(120°)) = (6·cos(120°), i·6·sin(120°)) = (6(-0.5), i·6·√3/2)
= (-3, 3√3 i)
You may want the (x, y) coordinates written as (-3, 3√3).
___
In the complex plane, this is -3+i·3√3.

Answer:
The x-intercept is 5.
Some people prefer you right it as a point (5,0).
Step-by-step explanation:
The x-intercept can be found by setting y=0 and solving for x.
Just like to find the y-intercept you can set x=0 and solve for y.
Let's find the x-intercept.
So we will set y=0 and solve for x:
3x-9y=15
3x-9(0)=15
3x-0 =15
3x =15
Divide both sides by 3:
x =15/3
x =5
So the x-intercept is (5,0).
