Getting ready for Systems of Equations

_{What is the y-intercept of the line?}

• y = 1/2
• y = 1
• y = -1/2
• y = -1

Solve for x.

2x + 1 = 4x - 1

• x = 1

• x = -1

• x = 0

• x = 3

which point works in the equation: x - 2y = 4

• (-2,1)

• (4,-1)

• (2,-1)

• (4,1)

What is the solution to the system?

• (3, -1)
• (2, -6)
• No Solution 
• (6, -2)

Solve the equation.

3x - 16 + 4x = 5

• -3

• 3

• 11/7

• -21

Which point works in both equations?

5x + 3y = 7

y + x = 3

• (4,1)

• (4,-1)

• (-1,4)

Where do the lines intersect?

• (0, 3)

• (1, -1)

• (-3, 1)

• (1, 3)

Where do the lines intersect?

• (1,1)

• -2

• (1, 2)

• (1, -1)

Where will the lines intersect?

• (1,0)

• Never

• (10,10)
