Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is - 3/4?

You need to draw out the slope on a piece of graph paper and u can figure it out

In order for a line to be parallel it must have the same slope of - 3/4

in order for a line to be perpendicular it must have the inverse of the slope which would be 4/3

if it is neither of the cases listed above it is neither parallel nor perpendicular
