Describe the slope of the line. Then find the slope using two points. helppp step by step explanation

Step-by-step explanation:

Hi,

Describe the slope: This is a horizontal line. Slope measures the steepness of a line, since this is a horizontal line with no change whatsoever, the slope must be 0.

Calculate: (-1,-2) (3,-2)

Change in y over change in x

-2 - (-2) = 0

3 - 1 = 2

0/2 = 0

The slope is 0

Hope this helps <3

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
