The correct representation of the situation in the image is the first graph. So, the correct option is C.
The correct representation of the situation in the image is the first graph. The graph shows a linear relationship between the number of pounds of apples purchased (x) and the total cost (y). The slope of the graph is 2, which means that the cost of apples increases by $2 for every pound purchased. The y-intercept of the graph is -2, which means that there is a fixed cost of $2 even if no apples are purchased.
The other representations are not correct. The table does not show a linear relationship between x and y.
The equations y = 2x and y = x + 2 are also not correct, because they do not have a y-intercept of -2.
Therefore, the correct answer is: c)
