1. solve the following system of equations by graphing.
x + 2y = 8
x + 2y = -4
what is the solution?
(3, 5), no solution, infinite solutions, none of the above
2. the ordered pair (4,2) is a solution to the system of inequalities below.
y> -3x+2
y< 2x+1
true or false
3.when solving the system by substitution, what would you plug into the second equation for the letter x?
x+2y=4
2x+2y=6
x = 2, x = 4-2y, x = 4, x = 2y+4
4. there is no solution to the system below.
2x + 4y = 8
x + 2y = 6
true or false
