Direct Variation A relationship between two variables in which the data increase or decrease together at a constant rate
Linear Equations An equation whose solutions form a straight line on a coordinate plane
Point- Slope Form The equation of a line in the form of y-y1=m(x-x1), where m is the slope and (x,y) is a specific point on the line
Slop-Intercept A linear equation written in the form y=mx+b, where m represents slope and b represents the y- intercept
Rate of Change The ratio of the change in the output value and change in the input value of a function
Slope A measure of the steepness of a line on a graph; the rise divided by the run
X- Intercept The x coordinate of the point where the graph of line crosses the x-axis
Y- Intercept The y-coordinate of the point where the graph of a line crosses the y-axis
Unit Rate A rate in which used the second quantity in the comparison is one unit
Proportional Relationship A relationship between inputs to outputs in which the ratio of inputs and outputs is always the same.
