What is the most appropriate first step for solving the system of equations?

y = 3x - 6

y= -2x + 16

• 3x - 6 = -2x + 16

• y = 3(-2x+16) - 6

• y = -2(3x - 6) + 16

• y = y

Y = 1/3x +3 and Y = 1/3x -3 will create

• lines that cross at the origin

• horizontal lines

• vertical lines

• parallel lines

Your ordered pair should look like

• (X, Y)

• (Y, X)

• (Always (0,0)

• Whichever variable you solve for first is listed first

Solve the following system by graphing.  What is the solution?

• (-4, 2)
• (4, 2)
• (2, -4)
• (2, 4)
