To find:
The value belongs in the green box
Solution:
We have,
...(i)
...(ii)
Adding (i) and (ii), we get
So, the value for the first black is 2x. It means the value belongs in the green box is 2x.
The values of three blanks are 2x, 0 and 13 respectively.
Therefore, the correct option is B.
The x-intercept is the point where the line crosses the x-axis. That point has a y-coordinate of 0. The coordinates of the x-intercept are (-2, 0). You are also given point (-4, 6), so you have two points on the line.
You can use the two-point form of the equation of a line to find its equation.
