Examine the system of equations.
11Alexandr11 [23.1K]
<h3><u>Explanation</u></h3>
  • Given the system of equations.

y =  -  \frac{1}{4} x - 2  \\ x = 4

  • Substitute x = 4 in the first equation.

y =  -  \frac{1}{4} (4) - 2 \\ y =  - 1 - 2  \\ y =  - 3

We have both x and y values. Therefore, we can answer in coordinate point form.

<h3><u>Answer</u></h3>

<u>\large \boxed{(4, - 3)}</u>
