Question

How do you write `y-7=4(x+4)` in standard form?

Answer 1

`4x-y=-23`

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"`

`"given "y-7=4(x+4)`

`"distribute and rearrange into this form"`

`y-7=4x+16`

`rArr-7-16=4x-y`

`rArr4x-y=-23larrcolor(red)"in standard form"`
