Expanding the walls of our classroom. This is an interactive learning ecology for students and parents in our Algebra 2 class. This ongoing dialogue is as rich as YOU make it. Visit often and post your comments freely.
Ordered Pairs- Numbers written in ( ) ex: (3,2) - the order is important - it is a point on a graph
Origin- The ordered pair (0,0) on a graph. - it is where the x axis intercepts the y axis.
X axis- The horizontal line on a graph.Y axis- The vertical line on a graph.
Plot-when you mark an ordered pair on a graph.
Components- An ordered pair has two numbers in it, those numbers are the components.ex: (3,2)3 and 2 are the components.
Coordinate-A coordinate is a point on a graph.
Quadrant- There are 4 quadrants on each graph. They go counter clock wise.
Graph of an equation- Are the ordered pairs that make an equation true.
X-intercept - where a line intercepts the x-axisY-intercept - where a line intercepts the y-axis
Rise/Run - is how you find the slope of a line.Slope = m
You find the slope of the line by doing y - y1 over x-x1
Or you could also do y1- y2 over x1- x 2, either way is fine as long as you stay consistent!
