What is a slope triangle and how do we use it to determine slope

The video tutorial explains the concept of slope triangles, emphasizing their role as right triangles used to determine the change in distances between two points. It covers how to use slope triangles to find horizontal and vertical distances, and how these can be applied to calculate the slope of a line on a graph. The tutorial provides practical examples and techniques for reading graphs to determine slope, highlighting the importance of understanding the direction of the slope for accurate calculations.

What is a key characteristic of a slope triangle?

• It is an equilateral triangle.

• It is a right triangle.

• It is an isosceles triangle.

• It is a scalene triangle.

How can you determine the horizontal distance between two points using a slope triangle?

• By measuring the horizontal leg.

• By measuring the vertical leg.

• By measuring the angle.

• By measuring the hypotenuse.

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

• The line is vertical.

• The line is moving downwards from left to right.

• The line is moving upwards from left to right.

• The line is horizontal.

What is the first step in creating a slope triangle on a graph?

• Draw a square around the points.

• Draw a circle around the points.

• Draw horizontal and vertical lines through the points.

• Draw diagonal lines through the points.

How do you determine the slope of a line using a slope triangle?

• By dividing the vertical distance by the horizontal distance.

• By multiplying the vertical and horizontal distances.

• By adding the vertical and horizontal distances.

• By subtracting the horizontal distance from the vertical distance.

What should you do if the line is going down from left to right?

• Consider the slope as negative.

• Consider the slope as undefined.

• Consider the slope as zero.

• Consider the slope as positive.

When reading a graph, what is a simple method to find the distance between points?

• Use a ruler to measure the distance.

• Use a protractor to measure the angle.

• Count the units between the points.

• Estimate the distance visually.
