find equestion of the line which is perpindicular the line y=5x+9 and has y-intercept=6
Given
y=5x+9
Compare above equatoin with Standard Equation of the Straight line
y=mx+b
Slope m = 5
Since lines are perpendicular, multiplication of their slopes will result in (-1) therefore slope of the required line is (-1/5) and we have been given y-intercept 6 of the required line
y=-(1/5)x+6
y=-x/5+6
Above equation is the equatoin of the required line.
Red line = Given Line
Green line = Required Line
