Answer: [tex]y = -2x + 9[/tex]

Step-by-step explanation:

The formula for finding equation of line given slope and one point is given as :

[tex]y - y_{1} = m ( x - x_{1} )[/tex]

[tex]x_{1}[/tex] = 1

[tex]y_{1}[/tex] = 7

[tex]m = -2[/tex]

substituting the values into the equation , we have :

[tex]y - 7 = -2 ( x - 1 )[/tex]

[tex]y - 7 = -2x +2[/tex]

[tex]y = -2x + 2 + 7[/tex]

[tex]y = -2x + 9[/tex]
