Answer:

  • One solution: (0.4, -4.8)

Step-by-step explanation:

Given equations

  • y = -2x - 4
  • y = 1/2x - 5

This system has one solution since the two lines represented by the equations have different slopes.

Solution:

  • -2x - 4 = 1/2x - 5
  • -2x - 1/2x = -5 + 4
  • -2.5x = -1
  • 2.5x = 1
  • x = 1/2.5
  • x = 0.4

And y is:

  • y = -2*0.4 - 4 = -4.8

The point is:

  • (0.4, -4.8)
