MATH 1003?
A parabola.
X=-b/2a
You can either measure or estimate the coordinates visually from the graph, or solve the equation underlying the graph.
You should always use the vertex and at least two points to graph each quadratic equation. A good choice for two points are the intercepts of the quadratic equation.

The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
The equation 0 equals 0 is an identity and contributes absolutely nothing to the part of the graph that you should shade or not. The tautological statement can be ignored.
A linear equation ?
The slope of the graph of that equation is -1.
Same way you graph y = -4x - 0.5
Just swap the letter around in the formula that you are given!
the graph is moved down 6 units
The graph shifts downward (negative y) by 9 units.
