Question

how can you verify that
3x-2y=10
x+2y=-2
is interesting??​

Answer 1

Given :-

$3x - 2y = 10 \\ x + 2y = - 2$

R.T.P :-

Whether there are intersecting or not...

Solution :-

For intersecting lines the rule is

$\frac{a1}{a2 } is \: not \: equal \: to \frac{b1}{b2}$

So, substituting a1 = 3 ; a2 = 1 ; b1 = -2 ; b2 = 2,

we get

$\frac{3}{1} \: is \: not \: equal \: to \: \frac{ - 2}{2} = - 1$

So, it is intersecting lines ....
