Answer:

$\frac{3}{1}$ or 3

Step-by-step explanation:

To find the slope find two coordinates and set up the equation $\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$

For the coordinates (0,2) and (2,8) y2 is 8 and y1 is 2. x2 is 2 and x1 is 0. $\frac{8_{}-2_ }{2-0_ }$ you have to do subtraction first. 8-2 = 6 and 2-0 = 2

Now we have the equation $\frac{6}{2}$

this can be simplified to $\frac{3}{1}$

How to find the radius of a sphere when given the volume?

cupoosta [38]

Multiply the volume by 3. For example, suppose the volume of the sphere is 100 cubic units. Multiplying that amount by 3 equals 300.

Divide this figure by 4π. In this example, dividing 300 by 4π gives a quotient of 23.873.

Calculate the cube root of that number. For this example, the cube root of 23.873 equals 2.879. The radius is 2.879 units.
