Question

For wht valied of m and n the equations 2x+ny-4 and 4x-5y+m represents on same straight line

Answer 1

hii....

for these equation if

$\frac{a1}{a2} = \frac{b1}{b2} = \frac{c1}{c2}$

so...by comparison of both the equation we get

$\frac{2}{4} = \frac{n}{ - 5} = \frac{ - 4}{m}$

we get...

n = -2.5

and m = -8

Hope it helps....❤❤
