Of the three lines in the graph, one has slope 1, one has slope 2, and one has slope . Label each line with its slope. First, what is the slope of the black line?

a. 1
b. 2
c. 1/5

Each time the line makes a “stop” at an intersection of graph lines, make a point. Count how many it takes to go up and across from one point to another. Think of it as a fraction: top number is how many it takes to go up, bottom number is how many it takes to go across. If top number is going up, then it is positive. If it is going down, it is a negative number. So the answer is STEEPEST slope is 2, LEAST steep is 1/5, and the MIDDLE one is 1.
