To determine which graph best represents Samantha's typing speed of 50 words per minute, we need to look for a linear graph where the slope represents the rate of typing.
The slope of a graph indicates how much the dependent variable (in this case, the number of words typed) changes with respect to the independent variable (time in minutes). If Samantha types 50 words per minute, the slope of the graph should be 50.
You should look for a graph where for every minute that passes on the x-axis (time), the number of words on the y-axis increases by 50. If one of the graphs clearly shows this linear relationship with a slope of 50, that would be the correct representation.
Since I cannot visually interpret the graphs you mentioned, check for any graph that shows a straight line that rises by 50 units on the y-axis for each increase of 1 unit on the x-axis.
