The solution should satisfy both Eqs:
-5x - 7 = 4. (2,2).
-5*2 - 7*2 = -24. Therefore, (2,2) is not a solution.
Test the other point in both Eqs.
You'll find that neither point satisfies
both Eqs.
Determine if the ordered pair is a solution to the system.
-5x - 7y= 4
y= 1/2 x - 1
a. (2,2) b. (2, -2)
