Equation of a Line

The video tutorial explains the concept of lines on a coordinate plane, focusing on their role as solutions to equations. It covers the calculation and significance of slope, the slope-intercept form of a line, and how to graph lines using these concepts. Examples are provided to illustrate graphing lines with given slopes and intercepts. The tutorial also introduces the point-slope form and demonstrates how to convert it to slope-intercept form for graphing purposes.

What is the relationship between the slope and the direction of a line?

In what scenarios would a vertical line be considered undefined?

How can you find the equation of a line when given a slope and a point?
