If given a value that is plot along x-axis: 1. Find given value along x axis. 2. From this point, trace a straight line vertically (parallel to the y-axis) until it intersects with the line graph. 3. Then, trace a line horizontally (parallel to the x axis) from the intersect to the y-axis. 4. The value of y corresponding to the given x value is where the traced line intercepts with the y- axis.
