Economic practice question

I've been trying to graph this data for a while, I just wanted to know if this was done correctly?

Suppose demand for masks is QD 15— P. The supply of masks is Qs 2P
Set QD Qs and use algebra to find the equilibrium P and Q.
Equilibrium P — 5 and equilibrium Q = 10 . (Enter your answers as a whole number.)
Using these equations, show the demand and supply curves for masks on a sketch. (Hint:
Remember the equilibrium you found above is a point on both the supply and demand curves.)
1 using the line drawing tool, draw the demand for masks based on the equation QD = 15 — P.
Label the line 'DI
2.) Using the line drawing tool, draw the supply of masks based on the equation Qs 2P. Label
the line 'Sl
3.) Using the point drawing tool, indicate the equilibrium in the mask market. Label the point 'El
Carefully follow the instructions above and only draw the required objects.
