Question

Jabian buys pencils as souvenirs from his vacation to give to his friends. He starts with 90 pencils and gives away 15 each hour until he has no pencils left. Use the Segment tool to plot a graph representing the number of pencils Jabian has left to give away from the time he starts giving them away until he has no pencils left.

Answer 1

You'll have to adapt this problem statement to Brainly, as Brainly does not have the Segment Tool available.

"starts with 90 pencils" implies that the y-intercept is (0,90).

"gives away 15 pencils" implies a slope of -15 pencils per unit of time

Thus, the # of pencils Jabian still has is   P(x) = 90 - (15 pencils / time unit)x
