Lesson: Slope of a Line through Two Points Mathematics • 8th Grade

Students will be able to

• understand the relationship between the slope of a line and the points that lie on the line,
• identify whether a line has a positive or negative slope from its graph,
• understand that the slope of a line is equal to the change in the -coordinate divided by the change in the -coordinate,
• find the slope of a line when given two points that lie on it,
• understand that the slope of the line connecting two points with the same -coordinate is zero,
• understand that the slope of the line connecting two points with the same -coordinate is undefined,
• find a missing coordinate value for a point that lies on a line when given another point and the slope of the line,
• understand that if a group of points are collinear, then the slope between any two of the points is the same,
• solving real-life application problems.
