Is this equation linear: 2x+5xy-3=0

What is linear equation?

An equation between two variables that gives a straight line when plotted on a graph.

2x + 5xy - 3 = 0

x (2 + 5y) - 3 = 0

x (2 + 5y) = 3

2 + 5y = 3 / x

5y = (3/x) - 2

y = ((3/x) - 2) / 5

According to the graph i don't think it's a linear equation.
