A) y = 4 - x
B) y = x + 2
C) y = 2x - 1
D) y = 3x
Hallamos intersecciones.
y = x + 2 y = x + 2
• y = 0 + 2 • 0 = x + 2
• y = 2 • x = -2
y = 4 - x y = 4 - x
• y = 4 - 0 • 0 = 4 - x
• y = 4 • x = 4
y = 3x y = 3x
• y = 3 × 0 • 0 = 3x
• y = 0 • x = 0
y = 2x - 1 y = 2x - 1
• y = 2 × 0 - 1 • 0 = 2x - 1
• y = - 1 • x = ½
