Samantha and Josh want to know when Josh will weigh more than Samantha. Josh currently weighs 31 pounds and expects to gain on average 6 pounds per year. Samantha currently weighs 45 pounds and expects to gain 4 pounds per year. a) let y be number of years and w= current weight in pounds. Write two linear equations to model Samanthas and Josh’s weight over time. b) Graph the linear equations using either points or the slope and dependent intercept. Be sure to label the axes and units
