Q. 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 x months.Complete the equation for the relationship between the weight and number of months.y=□
Calculate weight gain: Determine the amount of weight gained over the 8 months.The sumo wrestler started at 90 kilograms and weighed 138 kilograms after 8 months. To find the weight gained, we subtract the starting weight from the final weight.Weight gained = Final weight − Starting weightWeight gained =138kg−90kgWeight gained =48kg
Find rate per month: Calculate the rate of weight gain per month.To find the rate of weight gain per month, we divide the total weight gained by the number of months.Rate of weight gain per month = Number of monthsWeight gainedRate of weight gain per month = 8months48kgRate of weight gain per month = 6kg/month
Write linear equation: Write the equation for the relationship between the weight and the number of months.We know that the sumo wrestler gains weight at a constant rate, so we can express this as a linear equation with the slope representing the rate of weight gain per month and the y-intercept representing the starting weight.The general form of a linear equation is y=mx+b, where m is the slope and b is the y-intercept.In this case, m (the slope) is the rate of weight gain per month, and b (the y-intercept) is the starting weight.Therefore, the equation is:y=6x+90
