The following are true of slope:
- It describes the steepness of a line.
- It can also be referred to as the rate of change.
- It can be written as a ratio that compares the change in the dependent variable to change in the independent variable,
- It can be positive, negative, zero, or undefined.
- It is represented algebraically by the variable, m, in the formula y = mx + b.
- It can be determined using the formula m =
y2 - y1x2 - x1 when two points on a line are known.
- It can be determined using the sides of right triangles (slope triangles) on a graph.

Given the graph of y
+ 4, the y
-intercept is 4.
