Linear Equations in Standard Form
x-intercept
the point at which the line crosses the x-axis
constant function
A function like y = 5 that is the same regardless of the independent variable; graph is horizontal line.
standard form
Ax + By=C, where A, B, and C are not decimals or fractions, where A and B are not both zero, and where A is not a negative
equivalent
Different ways to write the same equation
Run
The horizontal change between any two points on a line
slope
The rate of change between any two points on a line. The ratio of the rise, or vertical change, to the run, or horizontal change.
Rise
The vertical change between any two points on a line
y-intercept
the point at which the line crosses the y-axis
slope-intercept form
y=mx+b, where m is the slope and b is the y-intercept of the line. It is the general way of writing an equation.
