What is a linear equation?

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x. It indicates how steep the line is and the direction it goes (positive slope means the line rises, negative slope means it falls).

Front

How do you find the y-intercept of a linear equation?

Front

What is the solution to a system of equations?

Back

The solution to a system of equations is the point (or points) where the equations intersect on a graph. It represents the values of the variables that satisfy all equations in the system.

Front

What does it mean if a system of equations has no solution?

Back

If a system of equations has no solution, it means that the lines represented by the equations are parallel and will never intersect.

Front

What is the formula for the slope between two points (x1, y1) and (x2, y2)?

Back

Front

What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you solve for x in the equation 2x + 3 = 11?

Back

To solve for x, subtract 3 from both sides to get 2x = 8, then divide both sides by 2 to find x = 4.
