Find the slope of Line A. What is the slope of Line B?

What kind of lines are A and B?

• Parallel

• Perpendicular

Two lines that are parallel will have ...

• Slopes that are opposite reciprocals

• No slope

• Slope that is the same

• none of the above

The equation of Line A is y = 3(x + 2) + 4. We know that the point (6, 3) is on Line B. Write an equation for Line B.
