  • Question 23 (request help)

    The table shows some ordered pairs that lie on a line. Which equations could represent the line? Select all that apply.

    • \(\text{y} = 4\text{x} – 2\)
    • \(\text{y} = -4\text{x} + 1\)
    • \(\text{y} – 2 = 4(\text{x} – 1)\)
    • \(\text{y} – 2 = 4(\text{x} – 6)\)
  • Question 24 (request help)

    After 4 hours of driving, Jan is 248 miles away from home. After 6 hours of driving, she is 372 miles from home. Select the correct values to complete the model below.

    slope: \(\cfrac{\text{?} - \text{?}}{\text{?} - \text{?}} = \cfrac{\text{?}}{\text{?}}\)

    What is the point-slope form of the line that represents this situation?
