Answer:
y+1=9(x+3)
Step-by-step explanation:
Since the equation for point slope form is y-y₁=m(x-x₁)
enter the given points (-3,-1)
y-(-1)=9(x-(-3))
y+1=9(x+3) <-- point slope form

Answer:
A lot of work, but CD=$15, Premium=$35, and Deluxe=$85
Answer:
A. He is right because 5 x 7 = 35 and 7 x 7 = 49. Since they are both multiplied by 7, they are equal.
Step-by-step explanation:
Explained in the answer.
Well, the first thing we need to do is divide 10 by 4. These teo numbers are the number of pens, and cost of them. So,
================================
10 / 4 = 2.5
--------------------------------------------------------
Now we have to use the answer we got, 2.5 which is the cost of 1 pen, and multiply it by 7.
================================
2.5 x 7 = 17.5
--------------------------------------------------------
This means that 7 pens cost <span>£</span>17.5
