Question

find the image of (1,-2) wrt to the straight line 2x-3y+5=0​

Answer 1

$\huge{\bold{\mathfrak{\pink{Answer:}}}}$

$2x-3y+5=0$

$\boxed{ slope (M)=\frac{-A}{b}}$

$M=\frac{\cancel{-}{2}}{\cancel{-}{3}}$

$\boxed{ x-x_1=M(y-y_1)}$

$x-1=\frac{2}{3}(y+2)$

$3(x-1)=2(y+2)$

$3x-3=2y+4$

$\huge{\boxed{\boxed{\bold{\blue{3x-2y-7=0}}}}}$
