Let's begin by listing out the information given to us:
The Get Well Soon Company
[tex]\begin{gathered} y=100+10x \\ \text{Rearranging the equation in the general form, we have it as:} \\ y=10x+100 \\ \text{When we compare this with the general equation of a straight line, }y=mx+b,\text{ we have:} \\ \Rightarrow Slope(m)=10 \end{gathered}[/tex]
The Mega Coverage Company
[tex]\begin{gathered} y=35x \\ \text{When we compare this with the general equation of a straight line, }y=mx+b,\text{ we have:} \\ \Rightarrow Slope(m)=35 \end{gathered}[/tex]
Comparing both companies, we will observe that The Get Well Soon Company has the lower rate and its rate is 10. Hence, option A is the correct answer
