Answer:
See answer for Step 6 below.
Step 7: the slope is "-1/2" (negative 1/2)
Step-by-step explanation:
Step 6: A negative slope means that as the value of the coordinate "x" increases,the value of the coordinate "y" decreases, and the rate of change for points on the line is therefore negative. The line goes "DOWN" as you read the graph from left to right.
In order to calculate the slope, we can use the triangle defined by the points (0, 5), (4, 3) and (0, 3) as shown in the attached image:
Where the "run" is from 0 to 4 , that is: 4 - 0 = 4
and the rise is negative (from 5 to 3: that is 3 - 5 = -2
Therefore, the rise over the run becomes: -2 / 4 = -1/2
