I hope you have an awesome day
Answer: Its the first one
You draw the graph of the line y=3x+5
but make the line dotted.
Label the line y>3x+5
Note that if instead we hade y≥3x+5 the line would be solid.
If you draw a line parallel to the y-axis through any x-value the value of y can be any on that vertical line that is above but not on the line y=3x+5
. So you end up with a 'feasible' region of solutions for y
Probably a ponytail or just your hair down.
To find the cost i think it would have to be c=6t because it is 6 dollars for 1 shirt if you find the constant of proprotionality and if you do 6 times for example 2 you will get 12 and 12 is the first cost on the graph as shown. Hope this helps and if it does please give me 5 stars please ( If you want) and a thanks.
