Y=mx+c where m is the gradient.
If the equation is perpendicular is -

Use y-y1=m(x-x1)
and you should get
y+1=-

(x+4)
4y+4=-3x-12
y=-<span>

Step-by-step explanation:
In a week, the parlor would make about $300 from milkshakes
The total amount the ice cream parlor makes in a week is dependent is the product of the number of days in a week , the number of milkshakes sold in a day and the price of a milkshake.
Total amount = number of milkshakes sold in a week x price of a milkshake
