y = x2 − 5x − 3
6x − y = −27

y = x2 − 5x + 3
6x − y = 27

y = x2 + 5x + 3
6x + y = −27

y = x2 + 5x − 3
6x + y = 27

Answer 1

Answer: y = x^2 + 5x + 3

6x + y = −27

Step-by-step explanation: I took the test and got it right :)

Answer 2

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)
