163. x = 4 is a line:

• parallel to y = –4
• parallel to x-axis
• passing through origin
• passing through origin

• x² + 4x - 3 = (x² - 1)
  

• x² = 3x + 4

⇒ The equation y = 3 in two variables can be

written as:

• 1· x + 1 · y = 3
• 0 · +1 · y = 3
• 0 · x + 0 · y = 3
• 0 · x + 0 · y = 3

Solution to the equation    

• lie on the x-axis
• in the 3^rd quadrant
• in the 4^th quadrant
• in the 4^th quadrant

• (x, y)
• (0, y)
• (x, 0)
• (x, 0)

The point of the form 

• 2x = y
• x = 2y
• x = y + 2
• x = y + 2
