Question

By drawing graphs check whether the pair of linear equations 3x+2y=5;2x-3y=7 represent intersecting, parallel or coincident lines.​

Answer 1

Answer:

A1/A2 ≠ B1 / B2

intersection

coincident lines

Step-by-step explanation:

using the formal

a1x + b1y + c = 0

a2x+ b2y + c = 0

3x + 2y = 5

1. 3x + 2y –5 = 0

2x – 3y = 7

1. 2x – 3y - 7 = 0

A1 = 3 and a2 = 2

B1 = 2 and b2 = –3

1. A1/A2 = 3/2
2. B1/B2 = 2/–3
