Question

Which system of equations is represented by the graph?

Answer 1

The answer is the third option, which is:
 y = x^2 + 5x + 3 
 6x + y = −27
 The explanation is shown below:
 1. When you solve this problem you have the following solution:
 x=-6
 y=9

 x=-5
 y=3

 2. As you can see the solution corresponds with the graph shown above.
 3. You can give value to the variable x of the first equation and values to the x of the second equation, and plot each point obtain. You will see that the parabola and the line, touch each other at the points (-5,3) and (-6,9)
