It is simlar to s bar graph except the "bars" are connected and the bars reprsent ranges instead of an actual number. The y axis is the constant (like time) and the x axis is variable (the ranges)

A graph which consists of short straight lines which keep changing direction. Example : a graph line which is inclined at say, 30 degrees to a horizontal, then changes direction instantly to a line which is say, inclined at 60 degrees to the horizontal , etc. If the shape of a graph is not a series of straight lines joined to each other, then it is not a step graph.
In the general category of communicating your results. most call it "analyzing results"
Since there are no powers of x or y or trigonometric functions or anything like that, you know that the graph is a straight line. So two points on the line is all that you need. Step 1: Let x = 0 and find y from the equation: y = -0 + 3 = 3 so one point on the graph (the y-intercept) is (0, 3) Step 2: Let x = 5 (or any other number) and find y from the equation: y = -5 + 3 = -2 so another point on the graph is (5, -2) Step 3: Join the two points. Done!
Example: draw the graph where y = 10 - x , from x = 0 to 5 step 1
