In the problem described below, assume that the relationship can be expressed as a linear equation in two variables, and use the given information to determine the equation. Express the equation in slope-intercept form. A new diet fad claims that a person weighing 170 pounds should consume 1,420 daily calories and that a 210-pound person should consume 1,600 calories. Let y represent the calories and x the weight of the person in pounds.
