Using a slope triangle to find the slope on a graph - Math teacher shows test answers

The video tutorial explains how to find the slope of a line by identifying coordinate points and calculating the change in Y values over the change in X values. It covers both visual and algebraic methods, including using slope triangles and subtraction to determine the slope. The tutorial emphasizes the importance of consistent order in subtraction and provides examples to illustrate the concepts.

What is the first step in finding the slope of a line on a coordinate grid?

• Subtract the y-values

• Draw a slope triangle

• Label the coordinates as X and Y

• Identify the origin point

How do you create a slope triangle on a graph?

• Draw a circle around the points

• Connect the origin to the points

• Draw a vertical and a horizontal line from two points

• Draw a diagonal line between two points

What is the result of moving down 4 units and right 5 units on a slope triangle?

• A slope of 5/4

• A slope of -5/4

• A slope of -4/5

• A slope of 4/5

When using the algebraic method, what is crucial to remember about subtraction?

• Subtract in the same order for both x and y values

• Subtract the larger number from the smaller one

• Subtract only the x-values

• Subtract in any order

What is the algebraic expression for finding the slope between two points?

• (Y1 - Y2) / (X1 - X2)

• (X2 - X1) / (Y2 - Y1)

• (Y2 - Y1) / (X2 - X1)

• (X1 - X2) / (Y1 - Y2)
