Question	Answer
The general form of an equation of a line	$ax+by+c=0$ where $a$ - $b$ and $c$ are three real numbers
The slope-intercept form (the slope-intercept equation) of an equation of a line	$y=mx+p$ where $m$ and $p$ are real numbers- $m$ being the slope and $p$ the $y$ -intercept. This form is unique for any line not parallel to the $y$ -axis.
The point-slope form of an equation of a line	$y-y_0=m(x-x_0)$ - where $m$ is a real number- the slope- and $(x_0-y_0)$ is a couple of real numbers- the coordinates of a point on the line. This form is not unique- as any point on the line can be used.
The intercept form of an equation of a line	$\dfrac{x}{q}+\dfrac{y}{p}=1$ where $p$ and $q$ are real nonzero numbers- respectively the $y$ -intercept and the $x$ -intercept
The slope (or rate of change) of the line connecting two points $(x_0-y_0)$ and $(x_1-y_1)$	$\dfrac{y_1-y_0}{x_1-x_0}$
