COUNT the slope of each line.

IF a line with a slope of
passes through point B. What other point lies on that line?Draw a line with a slope of -3 and a positive y-intercept.
All the points in this graph are on the same line. What is the slope of the line?
What are the values for a?

What are the values for b?

What is the x-value when y = 0?
