Use the image to answer the question.
A coordinate plane shows four quadrants. Three points are plotted on Quadrant 1, and three unlabeled points are plotted on Quadrant 2. The points are joined by lines to form one right triangle in each quadrant. Two points on quadrant 1 are unlabeled, and the third point is labeled upper C. The two unlabeled points are plotted at coordinates left parenthesis 4 comma 7 right parenthesis and left parenthesis 7 comma 7 right parenthesis. Point C is plotted at left parenthesis 7 comma 3 right parenthesis. The three points on quadrant 1 are joined by dotted lines to form a right triangle with its base on the top and perpendicular side on the right. The three points on quadrant 2 are unlabeled and are plotted at coordinates left parenthesis negative 7 comma 3 right parenthesis, left parenthesis negative 7 comma 7 right parenthesis, and left parenthesis negative 4 comma 7 right parenthesis. The three points on quadrant 2 are joined by solid lines to form a right triangle with its base on the top and perpendicular side on the left. Both the x-axis and the y-axis of the coordinate plane range from negative 8 to 8 in one unit increments.
If the right triangle shown is reflected across the y -axis, what is the coordinate of point C ?
