Given the information in the question, we want to write the equation of the line in the point slope form.
Mathematically, the point-slope form of the line can be represented as follows;
Where m represents the slope and the point (x1,y1) represents the given coordinates
From the question, x1 = 8 and y1 = -1
Substituting these into the equation above, we have;
y-(-1) = 8 ( x -8)
y + 1 = 8(x - 8)
So the equation of the line in the point-slope form is y + 1 = 8(x - 8)
