Slope Intercept Form

Warm-Up: 1.Complete the rounds activity from Wednesday 2.If you have completed the rounds activity then take the warm up worksheet from the front of the room and complete, once you complete the answer sheet is on the front cart in the folder to check your answers **You will have ten minutes to complete this, if you don’t finish I will post the rounds activity and the worksheet online for extra practice. Objective: To write and graph equations in slope intercept form

Rounds Review:

Round 4 Use the slope formula to find the missing coordinate:

X- intercept: Is the x-coordinate of a point where the graph crosses the x-axis and y = 0 Y-intercept: Is the y-coordinate of a point where the graph crosses the y-axis and x= 0 What are intercepts?

3x-2y = 12 How to find the intercepts given an equation

**To write an equation in slope intercept form we need to know the slope and the y- intercept! Slope- Intercept form!

Given an equation identify the slope and y- intercept:
