y−1,400=56(x+26)
Whose function has the smaller y-intercept?
Tim’s with a y-intercept of $2,700
Paul’s with a y-intercept of $2,856
Paul’s with a y-intercept of $2,800
Tim’s with a y-intercept of $2,780
1 answer
Tim's function has a y-intercept of $2,700, which is smaller than Paul's y-intercept of $2,856, Paul's y-intercept of $2,800, and Tim's y-intercept of $2,780. Therefore, Tim's function has the smallest y-intercept.
