Finding Slope and Y-Intercept

This video tutorial covers how to find the slope and Y-intercept from a table or two ordered pairs. It begins with a review of key concepts such as the definition of slope and Y-intercept. The lesson then provides a step-by-step guide on calculating the slope from a table by selecting two ordered pairs and using the slope formula. It also explains how to identify the Y-intercept from a table. The tutorial includes examples with fractions and practice problems to reinforce learning. By the end of the lesson, students should be able to find the slope and Y-intercept without graphing.

What is another method to find the slope besides using a graph?

• Using a compass

• Using a table or ordered pairs

• Using a protractor

• Using a ruler

What is the main objective of this lesson?

• To learn how to draw graphs

• To find the slope and Y-intercept from a table or ordered pairs

• To solve complex equations

• To memorize mathematical formulas

Where does the Y-intercept occur on a graph?

• Where the line crosses the X-axis

• At the highest point of the line

• Where the line crosses the Y-axis

• At the origin

What is the slope of a line often referred to as?

• n

• m

• c

• b

What is an ordered pair?

• A set of numbers representing a line

• A single number representing a point

• A set of three numbers representing a plane

• A set of two numbers representing coordinates

How do you find the slope from a table?

• By multiplying the X and Y values

• By dividing the X values by the Y values
