Question

Is xy + 8 = -2 linear?

Please teach me how did you find out, I need the method too.

Answer 1

Answer:

linear means an equation in which all the variables and components are raised to the power of one. so yea the equation you gave is therefore linear

Answer 2

Answer:

Linear

Step-by-step explanation:

xy + 8 = -2

=> xy = -2 - 8

=> 2+8 = -xy

=> 10 = -xy

=> 10/ y = - x

=> x= - 10/y

Since -10/y makes a straight line, it is linear.

Hence, proved.
