If Joanna worked 0 hours, she earns $0 (0,0). This is a linear equation because if you graph it, it'll make a straight line.

Since Alberto STARTED at 50 bench presses, (0, 50)
this makes it a non proportional situation.

(0,0)= proportional.


Theyre both Linear

Answer: Both the situation are linear.

Step-by-step explanation:

Since we have given that

Cost of per hour = $14

Let the number of hour be 'h'.

So, our equation becomes

[tex]Amount=A(h)=14h[/tex]

Number of pounds he started bench pressing = 50 pounds

Number of lbs added every week = 5

Let the number of weeks be 'w'.

So, our equation becomes

[tex]Amount=50+5\times w\\\\A(w)=50+5w[/tex]

Hence, both the situation are linear.
