Question
Find a general form of an equation of the line through the point A that satisfies the given condition.
A(8, −1); perpendicular to the line 5x − 5y = 4
A(8, −1); perpendicular to the line 5x − 5y = 4

the slopes of perpendicular lines are negative-reciprocals
the slope of 5x − 5y = 4 is 1
using point-slope , the A line is ... y + 1 = -1 (x - 8)
the slope of 5x − 5y = 4 is 1
using point-slope , the A line is ... y + 1 = -1 (x - 8)
