Question

A group of students went on a hike and measured the change in elevation over the length of the trail. They plotted these data on the graph shown below. They wanted a shorthand way to describe the line that represents the trail. Which slope-intercept equation describes the line? y - intercept = (0,2) slope = -1 A. y = -x + 2 B. y = x - 2 C. y = x + 2 D. y = -x - 2

1 Answer

  • The correct answer for this question is this one: "y = -x + 2"

     y - intercept = (0,2) slope = -1

    y = mx + b
    2 = -1 (0) + b
    b = 2

    so the equation of the line is
    y = -x + 2

    Hope this helps answer your question and have a nice day ahead.
