Answer:
Option b
Step-by-step explanation:
The following system of linear equations is shown
These are two different slope lines.
We find the cut points of both lines with the axes.
Cut with the x axis. (y = 0)
Cut with the y axis. (x = 0)
...................................................................
Cut with the x axis. (y = 0)
Cut with the y axis. (x = 0)
The solution to this system will be a point for which it is fulfilled that:
In the image, different graphs with intersections are shown.
Locate among the options, one that shows the two lines of the system of equations according to their intersections with the x and y axes.
Option b is the only one that shows the graph of the lines
Then, The point of intersection of both lines in the graph is:
(-5, 13)
Therefore the solution of the system of equations is: (-5, 13)
You can verify this by replacing the point in the relationship
Equality is satisfied
Finally the answer is the option b
You need to complete the square in x and in y,
First, group the x-terms and the y-terms separately.
Move the 10 to the right side by subtracting 10 from both sides.
Now complete the square in x and in y.
The constant you need to add to complete each square is the square of half of the coefficient of the x or y term. Make sure to add the constants to both sides of the equation.
