TRANSCRIPT Graphing Linear Functions in Standard and Slope Intercept Form Break Into Groups

• Group Leaders:– Elaina– Kaeori– Kyle– Megan– Alex N– Kevin S– Riley– Kali

You will need an expo marker for today.

Group leaders: Locate and move to a table.

Everyone else: choose a group leader. 4 to a group maximum Graphing in Slope Intercept

• The way the equation is written tells you all you need to know to graph the relationship

y = mx + b

slope y intercept y = - 1 y = - - 1 y = 3 -2 y = -3 -2 y = + 1 y = - + 1 y = 2x y = -2x Graphing in Standard Form

• This form does not tell us much about its graph. We need to use x and y intercepts to produce a graph.

• Substitute x = 0 to find the y intercept (0, y)

• Substitute y = 0 to find the x intercept (x, 0) x + y = -3       2x + y = 4 3x + 6y = 12 -2x + -3y = -6 -5x + 3y = -15
