graph
a picture of your data
What do graphs reveal?
graphs visual nature reveals patterns or trends that words and data tables can't
Name 3 types of graphs
line, circle, bar
horizontal axis
the x-axis or the graph line that runs left to right
vertical axis
the y-axis or the graph line that runs up and down
origin
the point where two axis cross
coordinate
a pair of numbers used to determine the position of a point on a graph
data point
the point showing the location of that intersection where two lines cross
line of best fit
a smooth line that reflects the general pattern of a graph
linear graph
a line graph in which the data points yield a straight line
What does a line of best fit emphasize?
it emphasizes the overall trend shown by all the data taken a s a whole
slope
the steepness of a graphline
slope equation
rise/run
What does the slope of a graph line tell you?
it tells you how much y changes for every change in x
What is a nonlinear graph?
a line graph in which the data points do not fall along a straight line
Why are line graphs powerful tools?
they are powerful tools in science because they allow you to identify trends and make predictions
