Finding Slope from Graphs and Points

This video tutorial introduces the concept of slope, explaining its importance in algebra for writing linear equations and graphing. It covers different types of slopes: positive, negative, zero, and undefined, using visual analogies. The tutorial demonstrates how to calculate slope using graphs and the slope formula with two points. It also explains how to find missing coordinates in ordered pairs using the slope formula. The lesson includes practical exercises to reinforce understanding.

What is the definition of slope in algebra?

• A type of algebraic expression

• A method for graphing equations

• A specific point on a graph

• A constant rate of change

What does a positive slope indicate about the direction of the line?

• The line moves upwards from left to right

• The line moves downwards from left to right

• The line is vertical

• The line is horizontal

What does an undefined slope look like on a graph?

• A line rising from left to right

• A horizontal line

• A vertical line

• A line falling from left to right

What does a zero slope indicate about a line?

• The line is horizontal

• The line is decreasing

• The line is vertical

• The line is increasing

If a line's slope is negative, what is its general direction?

• Upwards from left to right

• Downwards from left to right

• Horizontal

• Vertical

How do you calculate slope from a graph?

• Multiply the rise by the run

• Add the rise to the run

• Divide the change in x by the change in y

• Divide the rise by the run

How do you simplify the slope ratio 6/12?

• 1/2

• 1/4

• 2

• 3/6

What is the result of dividing zero by any number?

• The number itself

• 1

• 0

• Undefined

What is the slope formula when given two points?

• (x1 - x2) / (y1 - y2)

• (y1 - y2) / (x1 - x2)

• (x2 - x1) / (y2 - y1)

• (y2 - y1) / (x2 - x1)

In the slope formula, what does 'y2 - y1' represent?

• Intercept

• Slope

• Rise

• Run
