| Slope of a Line |
 |
A video that teaches the mathematical concept
of the slope of a line. I made it for one of
my NYU classes. Now I have my Master's in
Math Education and can start my teaching
career!

eform.php 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 written 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.
