Rise
Change in y between two points on a line.
Run
The Change in x between two points of a line.
Slope
A ratio of the change in y to the change in x between any two points on a line. It is a measure of the steepness of a line.
Slope-intercept Form
A linear equation of a non-vertical line written as y = mx + b, where m is the slope and b is the y-intercept.
Solution
The value of the variable that makes an equation true.
Solution of Linear Equations
--->
Solution Points
The graphical representation of an answer.
EX: the answer is x=1 and y=2
Standard Form
The equation of a line in the form of Ax By=C where A and B are both non-zero.
System of Linear Equations
A set of two or more equations with the same variables.
X-intercept
The point at which a line crosses the x-axis (or the x-coordinate of that point) is an x-intercept.
Y-intercept
The point at which a line crosses the y-axis (or the y-coordinate of that point) is a y-intercept.
