y=1/2x - 2

Step-by-step explanation:

The y-intercept is -2 and the slope of the line is 1/2. You can find the slope by using the rise over run method, which is the change in y over the change in x. In the points, x changed by +2, and y by +1, which is 1/2. Substitute that into the formula y=mx + b using one of the points to find the y-intercept, or b. You could use -4 = 1/2(-4) + b, solve for b, and you would get -2.

B - 523cm^3

Step-by-step explanation:

Volume of a sphere is

V = 4/3 * π * r^3

V - volume of the sphere

π - 3.142

r - radius of the sphere

We are provided with

π - 3.142

r - 5

Inserting this values to solve for the volume

V = 4/3 * π * r^3

V = 4/3 * 3.142 * 5^3

V = 1.33 * 3.142 * 125

V = 523.67 cm ^3

To the nearest whole number

V = 524 cm ^3
