Front

What is the Point-Slope form of a linear equation?

Back

y - y₁ = m(x - x₁) where m is the slope and (x₁, y₁) is a point on the line.

Front

What is the x-intercept of a graph?

Back

The point where the graph intersects the x-axis, also known as the solution or root.

Front

Define Slope in the context of a graph.

Back

The ratio of the change in y-values (rise) to the change in x-values (run), represented by the variable 'm'.

Front

What is the Standard form of a linear equation?

Back

Ax + By = C where A, B, and C are constants.

Front

What condition makes two lines perpendicular?

Back

Two lines are perpendicular if their slopes are opposite reciprocals of each other.

Front

What does the term 'Range' refer to in a function?

Back

The set of all possible output values (y-values) for the function.

Front

What is the Slope-Intercept form of a linear equation?

Back

y = mx + b where m is the slope and b is the y-intercept.

Front

What is a linear equation?

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.
