Answer 1

Step-by-step explanation:

a1x + b1y + c1 = 0

a2x + b2y + c2 = 0

a1 = 5, b1 = -4 and c1 = 8

a2 = 7, b2 = 6 and c2 = -9

a1/a2 = 5/7

b1/b2 = -4/6 = -2/3

c1/c2 = 8/-9

Here, a1/a2 not equal to b1/b2

Therefore, they are intersecting lines

Answer 2

Step-by-step explanation:

According to the question,

a1 =5, b1 =-4, c1 =8

a2 =7, b2= 6, c2 =-9

Now,

$\frac{a1}{a2} = \frac{5}{7} \\ \frac{b1}{b2} = \frac{ - 4}{6} = \frac{ - 2}{3} \\ \frac{a1}{a2} not \: equal \: to \: \frac{b1}{b2}$

The given pair of equation intersect at a point
