Answer:
4/3
Step-by-step explanation:
we know perpindicular lines intersec to create 90 degree angles. therefore the slopes must be the opposite reciporacle of one another
the reciporacle of -3/4 is -4/3
you then have to flip the signs giving you the "opposite" part which means -4/3 then goes to 4/3
in conclusion the slope must be 4/3
