Types of Problems: | 2 |
The Slope intuition exercise appears under the 8th grade (U.S.) Math Mission, Algebra basics Math Mission, Algebra I Math Mission and High school geometry Math Mission. This exercise cultivates the intuition of slope and how lines behave.
Types of Problems[]
There are two types of problems in this exercise:
- Graph a line with a certain slope: This problem provides a coordinate grid on which a line can be constructed. Users are expected to graph a line with a given slope.
- Adjust coefficients to make the line: This problem has a coordinate plane with two blue points. Users are is expected to adjust the slope and y-intercept using the manipulative to create the equation of the line.
Strategies[]
Knowledge of lines such as slope and uses of slope-intercept form can help to perform this exercise well.
- The slope formula is .
- It is not necessary to get fancy. It is possible to make a line positive or negative sloped by only moving one point and only moving it slightly. This is the first problem where research has found instances where pressing "Enter" can submit a correct answer with no work.
- On the Adjust coefficients to make the line problem it is recommended to change slope first by eyeballing, and then moving the y-intercept.
Real-life applications[]
- Linear equations show up often in business and many of the sciences.
- Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
