What is the slope of the line shown in the graph? A coordinate plane is shown. Points are graphed at negative 3 comma 2 and negative 1 comma negative 1. The points are connected by a line. −3 over 2 −1 over 2 3 over 2 Undefined

Answers

The slope of a line is the rate of change of the line

The slope of the line is -3/2

The points on the line are given as:

\mathbf{(x,y) = \{(-3,2)\ (-1,-1)\}}

The slope (m) is calculated as:

\mathbf{m = (y_2 - y_1)/(x_2 - x_1)}

So, we have:

\mathbf{m = (-1-2)/(-1--3)}

\mathbf{m = (-3)/(2)}

Rewrite as:

\mathbf{m = -(3)/(2)}

Hence, the slope of the line is -3/2

Damari inflates a spherical balloon to twice its original radius. Explain to Damari why the surface area is 4 Tims as big when the radius is doubled.

Answers

The easiest way is to show him the formula for the area of a sphere:

Area = 4 π (radius)²

That's a good thing to discuss, because it's a good thing to remember,
and discussing it will help him remember it.

The important part to look at is the part where it says " (radius)² " .
That tells you that if you multiply the radius by (Anything), then
the area is multiplied by (Anything)² .

Since he multiplied the radius by 2, the area was multiplied by (2)² = 4 .
Surface area is directly proportional to the square of radius.

Thus, when radius is doubled, Surface area becomes 2² = 4 times.
