Answer:
(a) The graph is shown below.
(b) Domain : [0,90]
(c) Origin represents the initial position of the truck.
Step-by-step explanation:
(a) Let no. of miles be y and no. of gallons be x. Then, initially x=0 and y=0 and when x=90 then y=660 . The equation of this determined by formula:
[tex]y-y_{1}=m\cdot (x-x_1) , m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{22}{3}\\y=\frac{22}{3}\cdot x [/tex]
So the corresponding graph for this equation is given below :
(b) Domain : [0,90]
(c) Origin represents the initial position of truck when no. of gallons used is 0 and no. of miles covered is 0
