Answer 2

Answer:
`y=8x-25`

Explanation:

Given

Line passes through
`(3,-1)\ \text{ and}\ (4,7)`

Equation of line when it passes through two points
`(x_1,y_1),(x_2,y_2)`

`\Rightarrow (y_2-y_1)/(x_2-x_1)=(y-y_1)/(x-x_1)`

Insert the values

`\Rightarrow (7+1)/(4-3)=(y+1)/(x-3)\\\\\Rightarrow (8)/(1)=(y+1)/(x-3)\\\\\Rightarrow 8x-24=y+1\\\Rightarrow y=8x-25`
