Question

Find m if (7,-3) is a solution of (y-3/7)=m(x-1/7

Answer 1

substituting the given(x,y) values in given equation.

$- 3 - \frac{ 3}{7} = m(7 - \frac{1}{7})$

$\frac{ - 24}{21} = m( \frac{48}{7})$

$m = \frac{ - 24}{21} \div \frac{48}{7}$

$m = \frac{- 24}{21} \times \frac{7}{48}$

$= - \frac { 1}{6}$
