Question

Se a reta r tem coeficiente angular – 6 e o coeficiente linear - 9, então a equação reduzida de r é: 
a. y = 9x + 6
b. y = -9x – 6
c. y = 6x – 9
d. y = - 6x – 9 ​

Answer 1

$\large\boxed{\begin{array}{l}\underline{\rm Equac_{\!\!,}\tilde ao~reduzida~da~reta}\\\sf y=mx+n\\\sf m\longrightarrow coeficiente~angular\\\sf n\longrightarrow coeficiente~linear\end{array}}$

$\Large\boxed{\begin{array}{l}\tt dados\begin{cases}\sf m=-6\\\sf n=-9\end{cases}\\\underline{\rm soluc_{\!\!,}\tilde ao:}\\\sf y=mx+n\\\sf y=-6x-9\\\huge\boxed{\boxed{\boxed{\boxed{\sf\maltese~alternativa~d}}}}\end{array}}$
