Match each term to its definition.
Linear equation
— match —
An equation whose unknown appears only to the first power, graphing as a straight line.
The measure of a line's steepness, found as change in y over change in x.
The point where a line crosses the y-axis, the value of c in y = mx + c.
The principle of doing the same operation to both sides of an equation.
