Answer:
y=-2/7x+6
Step-by-step explanation:
first write this in y=mx+b format, y=7/2x−2
then write the perpendicular line, which is the opposite & negative of m
y=−2/7x-2
then remove b
y=−2/7x+b
plug in the numbers
(7,4) y= 4 x=7
4=-2/7*7+b
b is 6
so put the numbers back in
y=-2/7x+6
hope this helps and have a great day
