Let y = ax + b be the eqaution of the line. We have :

{2a+b=04a+b=−3⇒{2a=−3b=−2a{2a+b=04a+b=−3⇒{2a=−3b=−2a⇒⎧⎨⎩a=−32b=3⇒{a=−32b=3

So, the equation of the line is y=−32x+3y=−32x+3

The answer is : (0 ; 3)

Let y = ax + b be the eqaution of the line. We have :

\(\left\{{}\begin{matrix}2a+b=0\\4a+b=-3\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}2a=-3\\b=-2a\end{matrix}\right.\)\(\Rightarrow\left\{{}\begin{matrix}a=-\dfrac{3}{2}\\b=3\end{matrix}\right.\)

So, the equation of the line is \(y=-\dfrac{3}{2}x+3\)

The answer is : (0 ; 3)
