Respuesta :
For this case we must find the point that Harold used to arrive at the following equation:
[tex]y = 3 (x-7)[/tex]
Starting from the fact that the equation of the point-slope form of a line is given by:
[tex](y-y_ {1}) = m (x-x_ {1})[/tex]
If we compare the standard equation with Harold's, we see that the slope of the line is [tex]m = 3.[/tex]
In addition, it is observed that [tex]x_ {1} = 7[/tex]and [tex]y_ {1} = 0.[/tex]
Then, the correct option is: Harold used the point (7,0)
ANswer:
When Harold wrote his equation, the point was used (7,0).
