b.(4, 0) and (12, 4)
c.(4, 1/5) and (25/3, 4)
d.none of these
Question 2:
Solve the system - hint ,use the addition method:
7x + 9y = 8
4x - 9y = 6
Choices:
a. (-10, 14)
99 11
b. (14, -10)
c. (8, -10)
d.none of these
Question 3
Solving Systems by Graphing and Substitution Solve by graphing. Indicate whether each system is independent, dependent, or inconsistent.
3y = x + 5
3x -9y = -10
Question 4
The Addition Method
Solve by addition. Indicate whether each system is independent,dependent, or inconsistent.
x + 3(y - 1 ) = 11
2(x - y) + 8y =28
