How do you write an equation in point-slope form for the given y-intercept (0, 5) and is perpendicular to the line with equation y = –3x + 1?
Red line represents this line - y = -3 +1
Blue line is the required line. This line is vertical to y = -3 +1 and passing through the point (0, 5)
Since the two lines are vertical, the product of their slopes is equal to - 1
The equation of the line is -
