That equation in standard form is y= 7/8x-37/8

Explanation:

First, you can distribute the 7/8 to the x and the -3:

y+2=7/8x-21/8

After that subtract both sides by two:

y+2-2=7/8x-21/8-2

y=7/8x-21/8-16/8

y= 7/8x-37/8

7x-8y=37

Explanation:

"the equation of a line in "color(blue)"standard form" is.

color(red)(bar(ul(|color(white)(2/2)color(black)(Ax+By=C)color(white)(2/2)|)))
where A is a positive integer and B, C are integers.

"rearrange " y+2=7/8(x-3)" into this form"

rArry+2=7/8x-21/8larrcolor(red)" distributing"

"subtract " 7/8x" from both sides"

y+2-7/8x=cancel(7/8x)cancel(-7/8x)-21/8

rArry+2-7/8x=-21/8

"subtract 2 from both sides"

ycancel(+2)cancel(-2)-7/8x=-21/8-2

rArry-7/8x=-37/8

"multiply through by " -8
