Mrs. Vincent had some water in a glass. She
measured with a ruler next to the glass and
recorded the level of the water from the table in
centimeters (cm). Next she added an ice cube
and measured again. She repeated this adding
and measuring and recorded her data in the
following graph.
C = 150 + 0.53m
150 – 0.53m = C
150 + C = 0.53m
C – 150 = m ÷ 0.53
