Question

Tranform to standard form: \displaystyle y-7= -2(x+2)

Answer 1

Given:

$y-7=-2(x+2)$

To transform the given equation into standard form,

$\begin{gathered} Ax+By=C\ldots\ldots\ldots..\text{ Standard form of linear equation } \\ y-7=-2(x+2) \\ y-7=-2x-4 \\ 2x+y=-4+7 \\ 2x+y=3 \end{gathered}$

Answer: 2x + y = 3
