Donald graphs the distance he walks over time the graph passed through the points (3, 12) and (4, 16)

Using a proportional relationship, it is found that:A. The slope of the line is of 4.B. The slope is the same over both segments.What is a proportional relationship?A proportional relationship is modeled as follows:y = kx.Hence a proportional relationship is a special case of a linear function, with slope represented by the constant of proportionality of k and intercept of 0.For the presented case, the two variables x and y are direct proportional, and thus the output variable y is obtained as the multiplication of the input variable x by the constant of proportionality k.In this problem, the relationship has two points presented as follows:(3, 12) and (4, 16).Hence the slope, which is the constant of the relation, is given as follows:k = 12/3 = 16/4 = 4.Given two points, the slope is given by the change in y divided by the change in x. Hence, over each segment, the slopes are given as follows:(1,4) and (3,12): m = (12 - 4)/(3 - 1) = 8/2 = 4.(3, 12) and (4,16): m = (16 - 12)/(4 - 3) = 4.Which are the same slopes.Missing InformationThe problem is given by the image at the end of the answer.A similar problem, also about proportional relationships, is presented at https://brainly.com/question/10424180#SPJ1
