Finding Slope given the Line

The video tutorial explains how to find the slope of a line on a coordinate plane. It begins with a question about selecting coordinates, emphasizing the use of solid numbers. The tutorial then demonstrates using the slope formula, y2 - y1 over x2 - x1, with chosen coordinates (15, 2) and (0, 1) to calculate the slope as 1/15.

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

• Draw a perpendicular line

• Find the midpoint of the line

• Identify two points on the line

• Calculate the distance between points

Why is it recommended to choose solid number coordinates when finding the slope?

• They are always positive

• They are closer to the origin

• They are easier to calculate with

• They are more accurate

Which of the following is a correct pair of coordinates used in the video?

• (5, 3) and (0, 0)

• (10, 5) and (0, 1)

• (15, 2) and (2, 0)

• (15, 2) and (0, 1)

What is the formula used to calculate the slope of a line?

• y1 - y2 / x1 - x2

• x2 - x1 / y2 - y1

• y2 - y1 / x2 - x1

• x1 - x2 / y1 - y2

What is the calculated slope of the line using the points (15, 2) and (0, 1)?

• 2

• 15

• 0

• 1/15
