Pitanje 1
1.

Estimate the solution of the system of equations from the graphical representation.

Enter the coordinate point with NO SPACES.

Solve the system by graphing.

Work carefully and precisely to ensure that your graph reveals the correct solution.

Graph 1: y=-x-7

Graph 2: y=2x+2

Solve the system by Graphing here.

  • Kliknite na karticu Grafikon (Grafikon 1, Grafikon 2 i tako dalje) za svaki grafikon koji trebate nacrtati.
  • Odaberite ispravnu vrstu grafikona.
  • Kliknite na pozadinu grafikona da biste dodali tačku. Dodajte dvije tačke da biste kreirali grafikon. Prevucite tačku ili unesite x i y koordinate da biste uredili njen položaj. Kliknite na tačku da biste je izbrisali.
  • Nakon što kreirate grafikon, možete označiti kućicu s isprekidanom linijom.
