Yes.
No, it is is a single point.
Yes.
2x = 3y + 10 is linear. !!!! In straight line form it is 3y = 2x - 10 y = (2/3)x - 10/3
It is a linear equation in one variable, y.
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
The system is simultaneous linear equations
It is not a linear function because it is missing x as the input variable
It is one linear equation in two unknown variables.
x = 3, y = 3
Yes it is, since it can be represented in the form y = mx + b
This is an equation of a line. There are an infinite number of solutions which are all points on the line. It is a linear equation.
