Question

the value of x and y for which line 2x+3y=11 intersectso y-axis are​

Answer 1

Answer:

2x + 3y = 11 ----(1)

x – 2y = (– 12) ----(2)

Multiply by 2 in equation (2) and after that subtract equation (2) from equation (1)

7y = 35

⇒ y = 5

From equation (1)

2x + 3 × 5 = 11

⇒ 2x = 11 – 15

⇒ 2x = (– 4)

⇒ x = (– 2)

So, x1 = (– 2) and y1 = 5

If equation x – 2y = (– 12) intersects the x-axis at P(x2, y2), then y = 0,

x – 0 = (– 12)

⇒ x = (– 12)

⇒ x2 = (– 12) and y2 = 0

Now, (x1 – x2 + y1 + y2)

⇒ – 2 – (– 12) + 5 + 0

⇒ – 2 + 12 + 5

⇒ 15

Correct answer is 15
