What shape does the graph of a linear relationship take?
a line
IWhat shape does the graph of a linear relationship take?
Linear = Straight line! So, a graph of a linear relationship is a straight line.
What a step graph?
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.
What does the line on a speed or time graph show?
The shape and slope of the line on a graph illustrates the qualitative and quantitative relationship between the variables plotted on the axes of the graph. Sadly, there is no such graph as a "speed or time" one.
How do you read a line graph?
Each point on a line graph in 2-dimensional space can correspond to an ordered pair of values for two variables which is observed. Or, if it is a fitted line graph, it is an estimated ordered pair.
