Answer:
C) 54.5
Step-by-step explanation:
to find the constant of this proportional x and y table;
first divide y by x.
eg. 163.5 divided by 3, which results in 54.5
next, to confirm this is our answer, we need to divide y by x once more.

hope this helped! have a great day/night!! :')
Perpendicular (opposite slope)
only you have to do it flip the original slop and change the sign
original slop is -3x (filp it)
and change the sign (negative) become (positive)
is the perpendicular slop of the original line
remember
opposite slop (perpendicular line)
Same slop (parallel line )
y intercept is doesn't matter will be same or will be different
hope it will help you
