The video tutorial explains how to determine the slope of a line using two triangles, a red and a blue one. It demonstrates the concept of rise over run to calculate the slope, showing that both triangles yield the same slope of 1/4, regardless of their size, as they lie on the same line.

What is the primary focus when determining the slope of a line?

• The length of the line

• The rise and run of the line

• The thickness of the line

• The color of the line

What does 'rise' refer to in the context of slope?

• The diagonal distance

• The vertical distance

• The total length of the line

• The horizontal distance

What is the 'run' in slope calculation?

• The total length of the line

• The vertical distance

• The horizontal distance

• The diagonal distance

• 1/5

How much does the blue triangle rise?

• 5 units

• 4 units

• 3 units

• 2 units

What is the run of the blue triangle?

• 18 units

• 16 units
