1. 5.7 SLOPE INTERCEPT FORM 2015-2016

2. OBJECTIVE: TO BE ABLE TO WRITE AND GRAPH AN EQUATION IN SLOPE INTERCEPT FORM Warm-Up: 1. Check last night’s homework 2. Complete handout on the front cart Agenda: 1. Check warm up and answer homework questions 2. Intro Slope intercept Form 3. Practice Activity

3. WHAT IS SLOPE INTERCEPT FORM? y=mx+b where m=slope, and b= y-intercept **Note: when you write something in slope intercept form your equation should appear as y=____x + ____

4. IDENTIFYING PARTS OF AN EQUATION:

5. HOW TO GRAPH AN EQUATION IN SLOPE INTERCEPT FORM: Step 1: Identify the slope and y-intercept **Remember: the y-intercept is an ordered pair?? Hmm…. What could it be? Step 2: Plot your y-intercept on your graph, and use your slope to create more points on your line. Then connect your points *You should always have a point before and after your starting point!!

6. USE SLOPE INTERCEPT FORM TO GRAPH:

8. How do we WRITE Equations in Slope Intercept Form?

9. I. WRITE AN EQUATION IN SLOPE INTERCEPT FORM GIVEN A GRAPH: Steps: 1.Find the slope. 2.Find the y-intercept 3.Substitute your slope and y- intercept into the equation y=mx+b

10. 1. Identify the slope m = 2. Identify the y-intercept (where does your graph cross the y-axis ) 3. Substitute your m and b into your slope intercept form equation. y =mx + b WRITE AN EQUATION IN SLOPE INTERCEPT FORM GIVEN A GRAPH:
