1. The first graph plots data from a soap density measurement laboratory. The slope of the line is the density of the soap.
1. __________ Calculate the slope of the line.
2. ______________ Determine the y-intercept of the line.
3. y = _________ x + __________ Write the y = mx + b slope-intercept equation for the line.
4. [float] or [sink] The slope of the line is the density of soap. If the density of the soap is less than one gram/centimeter³ then the soap would float. If the density of the soap is greater than one gram/centimeter³ then the soap would sink. Based on the above, will this soap float or sink?
