Graph the line that represents a proportional relationship between ddd and ttt with the property that an increase of 0.20.20, point, 2 units in ttt corresponds to an increase of 1.81.81, point, 8 units in ddd. what is the unit rate of change of ddd with respect to ttt? (that is, a change of 111 unit in ttt will correspond to a change of how many units in d? d? d, question mark)

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

Part 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 the form or

step 1

Find the value of k

we have

substitute

so

the linear equation is equal to

step 2

using a graphing tool

graph the line
