Two lines, a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0

If \(\frac{a_1}{a_2}\)=\(\frac{b_1}{b_2}\)=\(\frac{c_1}{c_2}\), then the lines coincide

If \(\frac{a_1}{a_2}\)\(\frac{b_1}{b_2}\)\(\frac{c_1}{c_2}\), then the lines are parallel

If \(\frac{a_1}{a_2}\)≠ \(\frac{b_1}{b_2}\)\(\frac{c_1}{c_2}\), then the lines intersect

Given line 2x + 3y - 8 = 0

(i) intersecting line:

3x + 2y – 6 = 0

(ii) parallel line:

4x + 6y = 15

(iii) coincident line:

4x + 6y – 16 = 0
