Identifying slope of a line

The  exercise appears under the 8th grade (U.S.) Math Mission. This exercise calculates the slope between two points.

Types of Problems
There is one type of problem in this exercise:


 * 1) Calculate the slope: This problem provides two solutions to an equation. The student is asked to use the solutions as points to find the slope between them in the coordinate plane.Sf2p1.png

Strategies
Knowledge of the slope formula and an ability to work with numbers through rationals are encouraged to ensure success on this exercise.
 * 1) The numbers on this exercise can be fractions and the answer has to be provided exactly with no rounding.
 * 2) The slope formula is $$\frac{y_2-y_1}{x_2-x_1}$$, where these are the x and y values of the solutions.

Real-life Applications

 * 1) Slope is an important concept for understanding the rates at which objects move and change.
 * 2) In a word, calculus can be thought of as being about slope. The derivative is literally the slope of a tangent line.
