Determine the y -intercept, b , of the additive relationship y=x−1 . Write the y -intercept as an ordered pair. Is option 1 or 2 correct? Option 1: The y -intercept is −1 and is represented by the ordered pair (−1,0) . Option 2: The y -intercept is −1 and is represented by the ordered pair (0,−1) . (1 point)
Option 2 is correct. The y-intercept is the point where the graph of the equation crosses the y-axis, which occurs when x = 0. Therefore, the y-intercept is the point (0, -1)
Write the equation for the additive relationship where the y -intercept is −7 . The independent variable is x and the dependent variable is y . Is option 1 or 2 correct? Option 1: The equation of the additive relationship is y=x−7 . Option 2: The equation of the additive relationship is y=x+7 . (1 point)
Option 1 is correct. The y-intercept is the point where the graph of the equation crosses the y-axis, and it is represented by the constant term (the term without the x variable). In this case, the constant term is -7, so the equation of the additive relationship is y = x - 7.
A new pizzeria charges $4.00 for a personal size cheese pizza. They then charge you $1.00 for each topping you choose to add to the pizza. Write an equation that represents the total cost of the pizza based on each additional topping. Is option 1 or 2 correct? Option 1: The equation of the additive relationship is y=x−4 . Option 2: The equation of the additive relationship is y=x+4 . (1 point)
Option 2 is correct. The base price of the pizza without any toppings is $4.00, so that should be represented by the constant term in the equation. Each additional topping adds $1.00 to the total cost, so it should be added to the equation as x (the number of toppings). Therefore, the equation of the additive relationship is y = x + 4.
