The equation of line is
Step-by-step explanation:
Since the line is perpendicular to the line passing through (-1,-2) and (5,8) the product of it's slope and the line is related as
Slope of line through (-1,-2) and (5,8) is
Now we know that general equation of line is given by
Applying value we get
The value of 'c' can be obtained as we know that the line is passing through (4,7)
Thus we have
