Write the equation of the line that is parallel to y-axis and passing

1.	Write the equation of the line that is parallel to y-axis and passing through the point (i) (4,0) (ii) (-2,0) (iii) (3,5) (iv) (-4,-3)
Answer» Slope of the line that is parallel to y-axis is infinity. Eq of the line parallel to y-axis passing through (a, b) is x – a = 0 (i) (4, 0) ⇒ x – 4 = 0 (ii) (-2, 0) ⇒ x + 2 = 0 (iii) (3, 5) ⇒ x – 3 = 0 (iv) (-4, - 3) ⇒ x + 4 = 0

Write the equation of the line that is parallel to y-axis and passing through the point (i) (4,0) (ii) (-2,0) (iii) (3,5) (iv) (-4,-3)

Answer»

Slope of the line that is parallel to y-axis is infinity.

Eq of the line parallel to y-axis passing through (a, b) is x – a = 0

(i) (4, 0)

⇒ x – 4 = 0

(ii) (-2, 0)

⇒ x + 2 = 0

(iii) (3, 5)

⇒ x – 3 = 0

(iv) (-4, - 3)

⇒ x + 4 = 0
