Answer: 
Step-by-step explanation:
Slope of two lines that are perpendicular to each other is 1.
If one line is
, then its slope = 3 [by comparing to the linear equation y= mx+c, here m=3]
Let n be the slope of the required line, then

Equation of line with slope n and passers through (a,b) is

Equation of line with slope n=
and passes through point ( 0,-4) :

Hence, Required equation : 
When two variables have an inverse relationship, the slope is negatively correlated.
You answer should be 8 and 11 maybe I don't know
Answer:
10x2y3 -4xy2
Step-by-step explanation:
Just take the like terms and separate them-
1) 4x2y3 - (-7x2y3)= 10x2y3
2)2xy2 - 6xy2= -4xy
3)-2y - (-2y)= 0y
Hope this helps :)
