Question

Consider the line y=2/3x-4 a line perpendicular to the graph of the line would have a slope of

Answer 1

The slope would be 2/3

Answer 2

-3/2

Explanation:

The slope of a line is its gradient. The equation shown here is y=mx+c. m is the gradient, therefore the gradient is 2/3. To find the perpendicular gradient you flip the sign (+ turns to -, - turns to +) and you switch numerator with the denominator.
