In this equation T is in degrees C and h is in cm so the units of m are (degrees C)/cm, degrees C per centimeter. Use two points in the table below to calculate m. Check with other pairs of points to verify that these points actually lie on a line. Use this value of m and one of the points in the table to write the equation T = mh + b.
Write back if you need more assistance,
