What is the equation of a line that passes through the point (8, 1) and is perpendicular to the line whose equation isy=−23x+5y=−23x+5 ?
Enter your answer in the box.
y = -23x + 5
The slope of a perpendicular line to this is (1/23)
So....the equation of this line passing through (8,1) is
y = (1/23) (x - 8) + 1
y = (1/23)x - 8/23 + 1
y = (1/23)x - 8/23 + 23/23
y = (1/23)x + 15/23
