COMPLETE THE DO NOW SILENTLY, INDEPENDENTLY, & IMMEDIATELY Do-Now Does the point (3, 7)

COMPLETE THE DO NOW SILENTLY, INDEPENDENTLY, & IMMEDIATELY Do-Now Does the point (3, 7) fit on the line Y = 2 X + 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!

Objective & Essential Understanding OBJECTIVE: SWBAT graph using the slopeintercept form of a linear

Objective & Essential Understanding OBJECTIVE: SWBAT graph using the slopeintercept 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.
