Use the scatter plot that shows the number of quarts of strawberries picked each hour. Use
the points (1, 73) and (8,41) to write the slope-intercept form of an equation for the line of
fit shown in the scatter plot.

you just switch the numbers basically so it would be 3/17

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
