Question

is 2x-5y==7 linear or not

Answer 1

2x-5y=7?

Answer 2

you can use algebra to solve for y - notice that none of the variables have a higher power than 1

Answer 3

or a power other than 1

Answer 4

a linear equation always take the form y= mx+b

Answer 5

good luck :)

Answer 6

i linear equation satisfies the following:

f(a+b) = f(a) + f(b)

f(ca) = c f(a) for some constant c

Answer 7

y = mx; is a linear equation.

y = mx + b; b not= 0, is an affine equation
