  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -2x - 6

2x + y = 5

Step 2: Solve for x

Substitution

  1. Substitute in y:                                                                                                  2x + (-2x - 6) = 5
  2. Combine like terms:                                                                                         -6 ≠ 5

Here we see that -6 does not equal 5.

∴ the systems of equations has no solution.
