A video demonstration of writing an equation to describe a table. Teaches students to be able to write the equation of a line and other basic functions when given points in a table. Concept explanation.

A triangle's altitude describes the distance from its highest vertex to the baseline. In right triangles, this is equal to the length of the vertical side. In equilateral and isosceles triangles, the altitude forms an imaginary line that bisects the base, creating two right triangles, which may then be solved.

Scientists and mathematicians dealing with direct and inverse relationships are answering the general question, how does y vary with x?Here, x and y stand in for two variables that could be basically anything. For example, how does the height that a ball bounces (y) depend on how high it’s dropped from (x)?By convention, x is the independent variable and y is the dependent variable.

Consider how you’d like students to show their work algebraically as they solve equations. As the equations become more complex in seventh and eighth grades, students often work vertically, so it is helpful to introduce this approach in sixth grade; however, with one-step equations, some students may benefit from seeing a horizontal approach.
