A linear equation is an equation in which each term has at max one degree. The function that represents Lucas’s situation is y=200-2x.
A linear equation is an equation in which each term has at max one degree.
Linear equation in variable x and y can be written in the form y = mx + c.
Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.
Given Lucas weighs 200 pounds. He starts a weight-loss program that helps him lose 2 pounds per week. Therefore, the rate at which Lucas is losing weight is 2 pounds per week.
Since the event is linear, therefore, the weight of Lucas after x weeks can be written as,
y = 200 - 2x
A.) The independent quantity is x, which is the number of weeks, and the dependent quantity is y, which is the weight of Lucas after x weeks.
B.) The function that represents Lucas’s situation is y=200-2x.
