Question

Graph the line that represents a proportional relationship between d and t with the property that an increase of 3 units in t corresponds to an increase of 888 units in d.
What is the unit rate of change of d with respect to t? (That is, a change of 111 unit in t will correspond to a change of how many units in d?)

Answer 1

Answer:

a) The unit rate of change of d with respect to t is equal to 1.6

b) the graph of the line in the attached figure.

Step-by-step explanation:

we know that

A relationship between two variables t and d represent a proportional variation if it can be expressed in a form of d/t = k

or d = kt

step 1:- find the value of k

we have

t = 5 , d = 8

k = d/t

k = 8/5

k = 1.6

so, the linear equation is equal to d = 1.6t

step 2 :- using a graphing tool  

graph the line d = 1.6t
