In this lesson, students learn to write the equation of a line given a
point on the line and the slope of the line, by using the point-slope
formula, which states that given a point (x1, y1) and a slope m, the
equation of the line can be writte...n as y - y1 = m(x - x1). For example, if a line passes through the point (3, -2), and has a slope of 4, its equation can be written: y + 2 = 4(x - 3). From here, the equation can be converted to either slope-intercept or standard form. Note that a horizontal line passing through a given point has the equation y = the y-coordinate of the given point, and a vertical line passing through a given point has the equation x = the x-coordinate of the given point.

In this lesson, students are given the coordinates of two points, and
are asked to find the slope of the line that passes through the points
(without graphing). To solve the problems in this lesson, students use
the slope formula, which states ...that m = (y2 -- y1) / (x2 -- x1). The
slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

This 3:15 lecture explains how to do y intercepts and provides an example. It moves rapidly and so the teacher may wish to stop the video to check for understanding.
