Conceptually I will be plotting my points in 3-D space. The x-axis can be the batch size, the y-axis the days into the year and the z-axis is the rate at which the jobs ran. This will look like a lot of points floating above the first quadrant. Then my task with the linear regression involving 2 variables is to draw a plane through the points that minimizes the squares of the distances from the plane to the points.

I can look up the details on that. So then will I be able to see that jobs run later in the year take longer even controlling for batch size? Will it be clear by the slope of the plane in one of the directions? Should I scale the ranges of the 2 variables to produce a square domain?
