Mastering the Slope Formula in 2 Minutes

Miss Marino and Mrs. Owens demonstrate how to find the slope of a line using the slope formula. They start by plotting two points on a coordinate plane and drawing a line. Observing the line's direction, they identify it as having a negative slope. The teachers explain the slope formula, m = (y2 - y1) / (x2 - x1), and label the coordinates. They substitute the values into the formula, simplify the result, and verify the slope by checking the line on the graph. The tutorial is designed to teach students how to calculate the slope in a concise manner.

What are the coordinates of the two points used in the lesson?

• (5, 2) and (-3, 4)

• (5, 2) and (3, -4)

• (-5, 2) and (3, 4)

• (5, -2) and (-3, 4)

What is the formula for finding the slope of a line?

• m = (y2 + y1) / (x2 + x1)

• m = (x2 - x1) / (y2 - y1)

• m = (x2 + x1) / (y2 + y1)

• m = (y2 - y1) / (x2 - x1)
