A linear equation in X and Y which represents a straight line can be represented in various forms
one of them is standard form $⇒ax+by=c$
so we have
$y+4=7\left(x-9\right)\phantom{\rule{0ex}{0ex}}y+4=7x-63\phantom{\rule{0ex}{0ex}}-7x+y=-67$
General form: ax+by+c=0 (a ,b ,c are Integers)
Standard form: ax+by=c (a ,b ,c are Integers)
Slope/intercept form: y=mx+c ( m and c are Real)
