WRITING LINEAR EQUATIONS FROM WORD PROBLEMS A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly and at a constant rate. After 8 months, he weighed 138 kilograms. He started at 90 kilograms. Let y represent the sumo wrestler's weight (in kilograms) after two months. Write an equation to represent the relationship between the weight and the number of months.
