Locate another point that lies on the line. On the Cartesian plane[ edit ] Lines in a Cartesian plane or, more generally, in affine coordinatescan be described algebraically by linear equations.
Graphing Linear Equations, Part 2 A more versatile approach to writing the equation of a line is the point-slope form, in which only two points are required, and neither needs to intercept the y axis. And we could keep doing that. This is a vertical line with undefined slope and passes through all points with x coordinate equal to h.
In Euclidean geometry[ edit ] See also: Order of Operations The order in which you do simple operations of arithmetic can make a big difference.
Page 50 Share Cite Suggested Citation: Slope This tutorial covers: In the example above, you were given the slope and y-intercept.
Engaging in the practices of engineering likewise helps students understand the work of engineers, as well as the links between engineering and science.
Traditionally, K science education has paid little attention to the role of critique in science. Third, attempts to develop the idea that science should be taught through a process of inquiry have been hampered by the lack of a commonly accepted definition of its constituent elements.
We consider eight practices to be essential elements of the K science and engineering curriculum: Yes, I have one on my phone, but I don't really want to have my phone out around my students all day.
Critical thinking is required, whether in developing and refining an idea an explanation or a design or in conducting an investigation.
Writing an Equation Given the Slope and Y-Intercept Write the equation for a line that has a slope of -2 and y-intercept of 5. In doing science or engineering, the practices are used iteratively and in combination; they should not be seen as a linear sequence of steps to be taken in the order presented.
This will define equation in the example above, part b. I always put a sticker on tests and quizzes that have earned an A. For scientists, their work in this sphere of activity is to draw from established theories and models and to propose extensions to theory or create new models.
A Framework for K Science Education: First, the equation might have exactly one solution. Solving Word Problems with Linear Equations Linear equations reflect the behavior of real-life phenomena.
