Answer: [tex]y+7x=499[/tex]
Step-by-step explanation:
The equation of a line passes through the points (a,b) and (c,d) is given by :-
[tex](y-b)=\frac{d-b}{c-a}(x-a)[/tex]
Hence, the equation of a line passes through the points (7, 450) and (14, 401) is given by :-
[tex](y-450)=\frac{401-450}{14-7}(x-7)\\\\\Rightarrow y-450=\frac{-49}{7}(x-7)\\\\\Rightarrow y-450=-7x+49\\\\\Rightarrow y+7x=49+450\\\\\Rightarrow y+7x=499[/tex]
