Review through November (extra credit)

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 vertical line test?

Back

The vertical line test is a method to determine if a curve is a graph of a function. If any vertical line intersects the graph at more than one point, then the graph is not a function.

Front

Write the slope-intercept form of a line with slope m and y-intercept b.

Back

The slope-intercept form is given by the equation y = mx + b.

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, indicating how steep the line is.

Front

Identify the solution set of a linear equation.

Back

The solution set of a linear equation consists of all the points (x, y) that satisfy the equation.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

How do you determine if a point is part of the solution set of an equation?

Back

To determine if a point is part of the solution set, substitute the x and y values of the point into the equation and check if the equation holds true.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input is associated with exactly one output, while a relation can have multiple outputs for a single input.

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed, typically in the form y = mx + b.

Front

What does it mean for a graph to be linear?

Back

A graph is linear if it can be represented by a linear equation and forms a straight line.
