  • Question 10 (request help)

    State the x- and y-intercepts of the equation \(\text{y} = \cfrac{2}{3}\text{x} - \cfrac{1}{3}\). Then use the intercepts to graph the equation.

  • Type below:

Copy and Solve State the x- and y-intercepts of each equation. Then use the intercepts to graph the equation on a separate sheet of grid paper.

  • Question 11 (request help)

    \(2\text{x} + 3\text{y} = 24\)

  • x-intercept =   
    y-intercept=

  • Question 14 (request help)

    Tiffany has 15 teaspoons of chocolate chips. She uses \(1\cfrac{1}{2}\) teaspoons for each muffin. The total amount of chocolate chips that she has left y after making x muffins can be given by \(\text{y} = -\cfrac{3}{2}\text{x} + 15\). Graph the equation. Then interpret the x- and y-intercepts.

  • Question 15 (request help)

    Use Math Tools Miriam has $440 to pay a painter to paint her basement. The painter charges $55 per hour. The equation \(\text{y} = 440 - 55\text{x}\) represents the amount of money y she has after x number of hours worked by the painter. Graph the equation. Then interpret the x- and y-intercepts.
