My teacher is asking me to write an equation in slope intercept form (y=Mx+b) and list 3 ordered pairs that makes the equation true. Can someone help?

James performed an experiment to see how adding different salts to water affects their freezing points. his data is shown below. concentration of salt solution (mol solute/kg water) freezing point for nacl solution freezing point for mgcl2 solution 0 0°c 0°c 2 -2.5°c -2.8°c 4 -6.0°c -7.5°c 6 -11.0°c -15.0°c 8 -16.5°c -35.0°c how are the freezing points related to the concentrations of the salt solutions?
