You didn't include the options, but one and only one line passes through two poins.
You can find the equation of the line that passes through two known points in this way:
[Y -Y1] / [X -X1] = [Y2 - Y1] / [X2 -X1]
in this case (X1,Y1) = (-2,2) and (X2,Y2) = (2,4)
=> [Y - (2) ] / [X - (-2) ] = [4 - 2] / [2 - (-2) ]
=> [Y -2] / [X + 2] = 2/4 = 1/2
=> 2 * (Y - 2) = X + 2
=> 2Y - 4 = X + 2
=> 2Y = X + 2 + 4
=> 2y = x + 6
=> y = x/2 + 3
So you must look the graph of that equation.
Some of the points of that graph are:
x y
-6 -6/2 + 3 = 0
-4 -4/2 + 3 = 1
-2 -2/2 + 3 = 2
0 0 + 3 = 3
2 2/2 + 3 = 4
4 4/2 + 3 = 5
So, you should find the correspondant graph easily.

Answer:
x=5
Step-by-step explanation:
We know that a pentagon is in total 540 degrees. From this, we add all other numbers and set them equal to 540 to solve for x.
So, after adding all the angles and setting them equal to 540, we get this.
21x+435=540
21x=105
x= 5
If you want, plug 5 into x and see if it adds up to 540 to check
21(5)+435=540
