Systems of Linear Equations Systems are two different equations that share a common point. There are three methods to finding a the point that works for both equations. The first method is called graphing. In my previous post I explained this method and how to…
Systems of Linear Equations Systems are two linear equations that combine to find a point on a graph. The point is one that both linear equations have in common or the point of intersection of two lines on a graph. The coordinate of the intersection…
Linear Equation Forms A linear equation is an equation that describes a linear line on a graph. A linear equation has no exponents. There are three ways to express a linear equation, and all three ways can represent the same line. There’s slope intercept form…
Finding the Function Parent Funciton The parent function is the basic simplified base of all linear equations involving slope. The parent function is positive, has a slope of 1, is neither steep nor shallow, 45 degree angle from the x line on a graph, goes…
Slope Formula and How to Use It Slope (m) is defined as rise divided by run. The rise is defined as the change in the y value between two coordinates. The run is defined as the change in the x value between two coordinates. This…
Function Notation – Graphs The way a line moves on a graph can mean different things for the results of an relation or function. If the line goes up: the y variable increases If the line goes down: the x variable increases and the y variable…
Functions Functions are a special type of relation. Functions are a type of relation were the x coordinate can only have one corresponding y coordinate. Example: {(-2,9)(-2,8)} this is not a function because the -2 has two y values. All functions are relations, but not…
Intercepts A typical coordinate is (x,y) or (4,6), (-9,3). Intercepts are the point in a graph where the coordinate/information intersects with the x-axis or y-axis. The coordinate for the x-intercept will always have the y as a zero (x,0). The coordinate for the y-intercept will…
Ugly Trinomials Ugly Trinomials are trinomials that don’t fit the simple trinomial formula ( + x + #). These trinomials can’t always be factored with the first three steps in factoring 1,2,3. In order to factor these trinomials we can use the box technique. The…
Factoring Factoring is the opposite of expanding like how division is the opposite of multiplication. There’s a three step method to find the answer when factoring with variables. This technique (taught by Mrs. Burton) is called Factoring 1,2,3. Factoring: Find if anything is in common…
