Answer:

y+4=-\dfrac{1}{3}(x-2)

Step-by-step explanation:

(x_1,y_1)=A(2, -4)\\\\x_1=2, y_1=-4\\\\m= -\dfrac{1}{3}

Sustituir en: y-y_1=m(x-x_1)

y-(-4)=-\dfrac{1}{3}(x-2)\\y+4=-\dfrac{1}{3}(x-2)

La ecuación de la línea punto-pendiente es:

y+4=-\dfrac{1}{3}(x-2)

\large{\blue{\bigstar}} \: \: {\underline{\boxed{\pink{\sf{ Area{\small_{(Rectangle)}} = Length \times Breadth }}}}} \: \: {\blue{\bigstar}}

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

<u>~ Calculating the</u><u> Area of Tiles </u>

{➙ \: {\sf{ Area = Length \times Breadth}}}

{➙ \: {\sf{ Area = 30 \times 20 }}}
