What is the slope of a line that is perpendicular to #3y+2x=6#?
A line is a negative inverse of it perpendicular line.
This means m(1)
Through manipulation of the equation we change it to
Using idea from earlier we flip the gradient and times it by -1.
If two lines are perpendicular then the result of multiplying the two gradients together always equals -1
Rearrange the equation to find the gradient:
