To determine whether the system of equations is independent, dependent, or inconsistent without graphing, we can solve the system algebraically using one of the methods such as substitution or elimination.
To begin, let's solve the system using the method of elimination:
1. Start with the given equations:
{y = 2x - 8 (equation 1)
{2x - y = 8 (equation 2)
2. Rearrange equation 2 to get y in terms of x:
2x - y = 8
-y = -2x + 8
y = 2x - 8 (equation 3)
3. Now we have the same equation for y in both equation 1 and equation 3:
y = 2x - 8
4. Since the equations are identical, the system is dependent. The dependency means that the two equations represent the same line, and there are infinitely many solutions that satisfy both equations.
Therefore, the system is dependent.
