Solving by Graphing
Solve by the following system by graphing
{ y = 2x + 1
y = -x - 2
What is (-1, -1)?
Solve the system for X ONLY using the elimination method:
2x - y = 3
3x + y = 2
What is x = 1?
y = x + 1
What is yes, because 2=2 √
Solve for x:
4x = 24
What is x = 6?
Solve the system of equations by graphing
{ y = 1/3x + 4
y = x + 4
What is (0, 4)?
Solve the system of equations for Y ONLY
{ y = 2x + 10
3y = -2x + 6
What is y = 4?
Does (4, -2) satisfy the equation
x + 2y = 0
In the expression 5x + 2 = -10, what is the value of the coefficient?
What is 5?
{ y = 2x + 4
y = 2x - 3
What is no solution?
Solve the system of equations using the elimination method:
{ x - y = 11
2x + y = 19
What is (10, -1)?
Does (1, 4) satisfy the system:
{ x = 1
y = 4?
By what factor should you multiply the first equation by in order to solve the system using elimination?
{ 4x + 9y = 9
-3x + 9y = 18
What is -1?
{ y = -x
y = x
What is (0, 0)?
Solve the system of equations using the elimination method:
-2x - 9y = -25
-4x - 9y = -23
What is (-1, 3)?
Does (1, 3) satisfy the system
{ 5x + y = 9
10x - 7y = -18
What is no, because 8 DOES NOT = 9 and -11 DOES NOT = -18
Simplify the following expression using the distributive property: 4(5x + y)
What is 20x + 4y?
Solve the system by graphing
{ y = 3
x = -3
What is (-3, 3)?
Solve the system of equations using the elimination method:
{ -6x + 6y = 6
-6x + 3y = -12
What is (5, 6)?
Does (-4, -4) satisfy the system
{ -3x + 7y = -16
-9x + 5y = 16
What is yes, because -16 = -16 √ and 16 = 16 √
Solve the following systems of equations using the method of your choice:
y = 3x + 4
y = -3x - 2
