A Point of Intersection
... 1. Have a group of three or four students “draw” specific equations/lines on a large grid on the floor with the robots dragging the string behind and have a student stand at the “solution”. 2. The rest of the class should then identify the solution/point. Split this larger group in two, assign each ...

9-5 Solving Quadratic Equations by Using the Quadratic Formula
... 9-5 Solving Quadratic Equations by Using the Quadratic Formula The Discriminant In the Quadratic Formula, the expression under the radical sign, b2 – 4ac, is called the discriminant. The discriminant can be used to determine the number of real solutions for a quadratic equation. Case 1: b2 – 4ac < 0 ...

Evaluating algebraic expressions:
... The substitution method is used to eliminate one of the variables by replacement when solving a system of equations. 1. Solve one of the equations for either "x =" or "y =". This example solves the second equation for "y =". 3y - 2x = 11 y = 9 - 2x 2. Replace the "y" value in the first equation by w ...

... Equations of a Trend Line A trend line is a linear equation (in our case) that represents the data shown. A trend line does not have to pass through all or any of the points. It just has to fit closely to most of the points. A good rule of thumb would be to have as many points above the line a ...
