Question

equations a x +by + C is equal to zero and dx + ey + C is equal to zero represent the same straight line if______________.​

Answer 1

Answer:

Step-by-step explanation:

The coefficients a, b, c, d, e and f of the two linear equations ax+by+c=0 and dx+ey+f= 0 need not satisfy the relationship a/d= b/e = c/f.

But if they do, then each ratio is equal to (a+b+c)/(d+e+f).

The above situation is true only if the lines represented by the two linear equations coincide, in which case, the two equations have infinite solutions.

Answer 2

$\huge\star{\underline{\mathfrak{Answer}}}$

• The relationship of straight line is here will be a/d=b/e=c/f.
• This relationship but does not seem to be equal because the coefficients do not match of both the equations.
• This relationship is only possible if ...ANSWER:

It is only possible when this relationship is equal to ...

(a+b+c)/(d+e+f)
