Linear Equations and Functions
Term | Definition |
---|---|
Constant Proportionality | A constant ratio of two variables related proportionally |
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. |
Intersecting Lines | Lines that cross at exactly one point |
