The point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).
<h3>What is point slope form?</h3>
The point slope form of a line is the expression of line which has a specified slope and passes through a point.
The point slope form is givne as,
(y-y₁)=m(x-x₁)
Here, m is the slope of the line, x₁ is the x coordinate of the point by which line passes and y₁ is the y coordinate of the same point.
The slope of a line is -5. This line contains the point A (2,-1). Thus, the point slope form is,
(y-y₁)=m(x-x₁)
(y-(-1))=-5(x-2)
(y+1)=-5(x-2)
Thus, the point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).

Answer:
you have to write the way you did the problem
Step-by-step explanation:
Answer:
The volume of the balloon is 18.84 inches³
Step-by-step explanation:
* Lets talk about the sphere
- Its a solid
- It has surface area = 4πr²
- It has no lateral area
- It has no faces
- It has no vertices
- It has no edges
- Its volume = (4/3) π r³
* In our problem the balloon shaped a sphere
- Its radius = 4.5 inches
- The value of π = 3.14
* Lets calculate its volume
∵ The radius = 4.5 inches
∵ π = 3.14
∵ The volume = (4/3) π r³
* Substitute the values of r and π in the formula
∴ The volume = (4/3) × 3.14 × 4.5 = 18.84 inches³
* The volume of the balloon is 18.84 inches³
