Question

Is -4x-8y=-3 a linea equation in two variables 

Answer 1

Yes, this is a linear equation. A linear equation is one that has the highest exponents on the variables as 1, regardless of the number of variables.

 

Example: 8a+2b-17c+2.6d =0 is a linear equation in 4 variables.

 

If the highest power is 2, it is called quadratic

 

example: 8a +2b-17c² +2.6d=12

 

Hope this helped.
