Write the equation of the perpendicular line with the points (-9,2) with the equation 3x-y=12

y=-1/3x-1

Step-by-step explanation:

Perpendicular lines have slope that are opposite sign and reciprocals

3x-y=12 has a slope of 3, therefore perpendicular line must have slope of -1/3

2=-9(-1/3)+b

2=3+b

b=-1

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.
