Linear Equations and Functions (y isolated) 3/12/2016 Heading TSWBAT: graph a linear equation using a table with y isolated. Students graph a linear equation and compute the x- and y- intercepts (e.g., graph 2x + 6y = 4). They are also able to sketch the region defined by linear inequality (e.g., they sketch the region defined by 2x + 6y < 4).
5
Solution of an equation Notes = an ordered pair (x, y) that makes the equation true. Determine whether the ordered pair is a solution to the equation. Ex. Rewrite the equation. Plug in x and y. Simplify. Is this true? Rewrite the equation. Plug in x and y. Simplify. Is this true? x y x y x y Now you try.

Steps to Graphing an Equation using points Notes 1. Make a xy-table. Let the values of x be 2, 1, 0, -1, -2. 2. Plug in each value of x and solve for y. 3. Plot each ordered pair on a graph. 4. Connect all of the dots with a line. - If the dots do not make a line you made a mistake.
8
Notes Graph the equation Just plug in all of the x’s. Plot the points. Connect the dots with a line. Ex.
