First recall that perpendicular lines have slopes that are the negative reciprocal of each other.
In other words, if one of the lines has a slope, then the slope of the perpendicular line is.
In your problem, you are given the line whose slope. The new perpendicular line will then have a slope, so using the slope-intercept form of the linear equation, we have:
To find the value of b (the y-intercept), substitute the x- and y-coordinates of the origin (0, 0).
Substitute x = 0 and y = 0.
so b = 0.
The final equation will be:
