A. The (x,y) coordinates where the equations y =4x and y = 2x - 1 intersect on a graph is the solution to that system of equations. When solving for this system of equations by substitution of y, the equation 4x = 2x -1 is obtained. So the x-coordinate obtained is both a solution to the equation 4x = 2x - 1 and the intersection point of the system of equations y = 4x and y = 2x - 1.
B. Idk about this part... Says to make a tables to solve for 4x = 2x - 1.
If you make a table for Eq. #1. y = 4x and Eq. #2. y = 2x -1 maybe..
#1. y = 4x
x ...... y
-4 .. -16
-3 .. -12
-2 .. -8
-1 .. -4
0 ... 0
1 ... 4
2 .... 8
3 ... 12
4 ... 16
the solution to 4x = 2x - 1 ; the x-coordinate is not an integer value so Idk what the point of this is.....
4x = 2x - 1
4x - 2x = -1
2x = -1
x = -1/2
not an integer..
C. You can solve the equation 4x = 2x - 1 graphically by graphing y = 4x and y = 2x - 1 and identifying the x-coordinate at the point of intersection.

A's y is = 1 and B's y is also 1
Check the picture below.
∡a has a vertical angle sibling of 40°, and vertical angles are always congruent.
∡b is the 3rd angle in a triangle, the other two are 40° and 90°, recall all interior angles in a triangle add up to 180°.
∡c is a linear angle, namely an angle on the same flat-line as another, and linear angles always add up to 180°.
