# Derivative as slope of a tangent line | Taking derivatives | Differential Calculus

Calculus-Derivative: Understanding that the derivative is just the slope of a curve at a point (or the slope of the tangent line). All Khan Academy content is available for free at www.khanacademy.org

# Ex: Determine if a Table Values Represents a Function

## By Mathispower4u

Ex: Determine if a Table Values Represents a Function

# Writing the equation of a line in any form

Point-slope and standard form

# Interpreting linear relationships

Sal discusses how we would go about making sense of the direction of a linear graph that represents a relationship between two real-world quantities.

# Recognizing functions from graphs

Sal explains why a vertical line *doesn't* represent a function.

# Recognizing functions from tables

Sal checks whether a table of people and their heights can represent a function that assigns a height to a name.

# Khan Academy: Linear Equation Application Problem

Get more practice with functions by watching this word problem. Here you must graph the equation and use it to find a specific output. Start by creating a table to get a range of values. You'll need several ordered pairs to create the graph!
