Answer 1

`\large {\boxed{ \sf{y = 2x + 5}}}`

Explanation:

Suppose the slope of the line is k.

So,

`\large {\bold {k = (7 - ( - 1))/(1 - (3)) = (7 + 1)/(1 + 3) = (8)/(4) = 2 }}\\`

So the line:

`\large \bold{ (y - 7)/(x - 1) = k = 2 } \\`

`\:`

So,

`\large \bold{y - 7 = 2(x - 1)}`

`\large \bold{y - 7 = 2x - 2}`

`\large \bold{y = 2x - 2 + 7}`

`\large \bold{y = 2x + 5}`

`{\rule{200pt}{4pt}}`

`\large \bold{-N} \frak{unx-}`
