Answer 1

$\large\boxed{\begin{array}{l}\rm O\,gr\acute afico\,passa\,pelos\,pontos\,A(-4,0)~B(0,3)\\\rm m=\dfrac{y_B-y_A}{x_B-x_A}\\\\\rm m=\dfrac{3-0}{0-(-4)}\\\\\rm m=\dfrac{3}{4}\\\underline{\sf Equac_{\!\!,}\tilde ao\,fundamental\,da\,reta}\\\rm y=y_0+m\cdot(x-x_0)\\\rm A\,reta\,passa\,pelo\,ponto\,P(x_0,y_0)\\\rm e\,tem\,coeficiente\,angular\,m\\\sf adotando\,o\,ponto\, B(0,3)\,temos:\\\rm y=3+\dfrac{3}{4}\cdot(x-0)\\\\\rm y=3+\dfrac{3}{4}x\end{array}}$
