Answer:they are not perpendicular because their slopes are not negative reciprocals.
Step-by-step explanation:
FG’s slope is 3/4 while HJ’s slope is 2/3. i just had this question on my test lol
The formula of the line is
y=mx + b
The likes goes through the point (0,0)
that means that y-int = 0, b=0
y=mx
So we need to find only slope.

The rule for multiplying similar bases with exponents is:
(a^b)*(a^c)=a^(b+c)
In this case you have:
(x^9)(x^2)
x^(9+2)
x^11
