Question

what is the slope of a line that is PERPENDICULAR to the line represented by the equation 3x+4y=12?
4/3
3/4
-3/4
-4/3

Answer 1

a

Answer 2

thanks

Answer 3

its 4/3

Answer 4

The slope of a perpendicular line is always the negative reciprocal of the original line's slope. y = 3x + 5. the slope of the perpendicular line would be -1/3.
For y =-(2/5)x -9. te slope of the perpendicular line would be 5/2. When you multiply the two slopes together the product will b negative 1, which is why they are called negative reciprocals.
