Find Equation of CD - Vidyadip

Question

Find Equation of CD

✓

Answer

AB and CD are Perpendicular to each other.
Thus,Product of their slopsn $=-1$
Slope of $A B \times$ Slop of $C D=-1$
$\Rightarrow$ Slope of $CD=8$
Now, from graph we have coordinates of $D=(-3,0)$
$\therefore$ Equation of line CD is given by
$y-0=8(x-3) $
$ y=8 x+24$
