Answer 3

any equation that has x AND y without any 'powers' (e.g. squared, cubed, squareroot) is a linear equation

Answer 4

i think its A

Answer 5

does A match the description I gave above?

Answer 6

yes

Answer 7

a linear function, is a function of this type:
\(y=ax+b\), where \(a,b\) are real numbers

Answer 8

so its B? @Michele_Laino

Answer 9
