<span>−8x+7y=25 is already in standard form, altho some people would prefer to re-write it as

</span><span>−8x+7y-25 = 0.

You have shared 4 equations here.  Next time, please separate them with commas or semi colons, or type just 1 equation per line, for increased clarity.  Thanks.</span>

Answer:

Answer is option d) <em>y</em><em>+</em><em>1</em><em> </em><em>=</em><em> </em><em>3</em><em>(</em><em>x-3</em><em>)</em>

Step-by-step explanation:

given \: that \: the \: equation \: is \: parallel \: to \\ y = 3x - 3 \\ 3x - y - 3 = 0 \\  the \: equation \: parallel \: to \: 3x - y - 3 = 0 \:  \: is \\ 3x - y + k = 0 \\ since \: it \: passes \: through \: (1, - 1) \\ 3(1) - ( - 1) + k = 0 \\ 3 + 1 + k \:  = 0 \\ k + 4 = 0 \\  k=  - 4 \\ the \: equation \: parallel \: to \: 3x - y - 3 = 0 \:   \\ \: is \:  \: 3x - y - 4 = 0 \\ it \: can \: also \: be \: written \: as \: y + 1 = 3(x - 3) \\ hence \: the \: answer \: is \: option \: d
