What is the convention for listing coordinates in Cartesian coordinates?

• y-coordinate first, then x-coordinate

• x-coordinate first, then y-coordinate

• It depends on the context

• Both coordinates simultaneously

What shape is formed when plotting the equation y = 2x - 1 on a Cartesian plane?

• A line

• A circle

• A triangle

• A curve

Why are equations like y = 2x - 1 called linear equations?

• They involve only one variable.

• They form a line when plotted on a Cartesian plane.

• They are easy to solve.

• They are named after a mathematician named Linear.

What happens if you plot all possible x values for the equation y = 2x - 1?

• You get a circle.

• You get a series of points.

• You get a line.

• You get a curve.
