This topic covers creating graphs from linear equations in two variables and various applications that relate to slope and a two variable graph. This series of six lessons involves converting from graph form to equation form, and vice versa. It also covers applications that can be modeled by linear equations in two variables. The topic also discusses horizontal and vertical lines.
This topic furthers the student’s understanding of linear equations in two variables.
This lesson introduces slope-intercept form and the y-intercept of a graph. The student then learns that they can find the slope from the graph as they already have and use this as the coefficient for x. Then, the student learns how to find the y-intercept and how to input it into slope-intercept form.
This lesson teaches the student how to plot points given slope-intercept form. It shows the efficiency gains over making a table.
This lesson shows the student how to graph applications that can be modeled by linear equations in two variables. The lesson shows the student how to graph an application problem.
This lesson teaches the student how to determine whether the slope of a line is positive or negative by looking at the graph.
In this lesson, the student learns how to interpret data that is graphed on the coordinate grid.
This lesson introduces the student to horizontal and vertical lines. It also describes how said graphs can be created via equations.
