A graph that shows the relationship between the two variables - ct and ctm. The x-axis of the graph is labeled as "X" and the y-axis is labeled "Ct". There are two lines intersecting at the top and bottom of the image, with the ct on the left side and the cm on the right side. The ct line is curved and has a point at the end, while the cm line is straight and has an arrow pointing towards the center. The graph also has two points labeled "E1" and "E3" on the top, which are connected by a dotted line. The point at E1 is labeled with a blue dot, and the point at CTM is marked with a yellow dot. There are also two blue dots on the dotted line, one labeled "XM" and another labeled "M". Overall, the graph appears to be a mathematical equation that shows that the relationship is between two variables, Ct and CTM, and that they are connected to each other.
