Question

I need help for B it’s due tomorrow :(((
B says: Which plan costs more per month? (hint: your answer should include the world “slope”)

Answer 1

For company S

• (0,5)
• (10,20)

$\\ \tt\hookrightarrow m=\dfrac{20-5}{10}=1.5$

For company Z

• (0,15)
• (10,20)

$\\ \tt\hookrightarrow m=\dfrac{20-15}{10}=0.5$

Company Z is better
