1. COMPLETE THE DO NOW SILENTLY, INDEPENDENTLY, & IMMEDIATELY
Does the point (3,7) fit on the line Y = 2X + 1?
Does the point (-1, 4) fit on the line Y = X + 4?
Does the point (2, 3) fit on the line Y = X + 2?
HINT: substitute the point values into the equation and see if both sides are equal!

2. Objective & Essential Understanding
OBJECTIVE: SWBAT graph using the slope-intercept form of a linear equation.
ESSENTIAL UNDERSTANDING: To graph from a slope intercept form equation, start from the Y intercept and use the slope to find new points on the line.

3. Review of Intercepts

4. Silently think about the answer & jot down your ideas
Review of Slope
Slope = Rise A slope of 3 = up 3 Run 1 over 1 Positive slopes go “uphill”; Negative slopes go “downhill”

5. What is the slope intercept form?
Y = mX + B Y = 3x + 2
