Graph+Linear+Equations

=Graphing Linear Equations=

- Powerpoint for identifying solution and using a table to generate solutions and graph a linear equations.

- Powerpoint for exploring the concept of x and y intercept, calculating the x and y intercept from an equation in standard form, and then using the intercepts to graph the equation.

- Powerpoint for exploring the connection between what students have already learned about slope and intercepts to identify the slope and y intercept from an equation in slope intercept form, and graphing the equation. A slide in the powerpoint links to "A Better Calculator" from desmos. With this calculator you can enter in the equation y=mx or y=mx+b and create sliders for m and b so that students can see what happens to the equation when you change the values of m and b.



Four stations for students to explore graphing linear equations- First one gives students one value in an ordered pair and an equations- they have to apply their equation solving skills. The second station has them completing tables of solutions for equations with one variable, and making observations about the graphs of those equations. The third station gives a linear equation and the graph of the equation. Students have to identify ordered pairs that are solutions and justify their choices. Then they have to extend that by identifying whether another point (not on graph) is a solution to the equation. The fourth station graphing two equations using a table of values and comparing the equations and graphs


 * Love the idea of this activity...Students start by picking an equation card and use the slope and y intercept to graph the equation. Then they pick a slope changing card, write their new equation, and graph the new line. Then they pick a y intercept changing card, write their new equation, and graph the new line. The first attachment is the recording paper and the second are the cards.
