The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
no
Yes.
No, y=x^2 + 2 is a quadratic equation. A linear equation is one in the form y=mx+b. A quadratic has a form y=ax^2+bx+c.
One linear equation in two variables cannot be solved. You can only express one of the variables in terms of the other.
A linear equation has no higher powers than 1. This is linear.
A linear equation represents a line. A linear inequality represents part of the space on one side (or the other) of the line defined by the corresponding equation.
y = 2x + 1 IS a linear equation!

Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
yes
Yes.
Yes.
yes
Yes.
Yes, the equation has a slope of 0.
A linear equation.
