Line passing through (4,-1) and (3,-2)

If you are trying to find the equation for a line passing through those points, first we subtract the points.

(4,-1)

-(3,-2)

(1, 1)

Then we find out what our slope (m) would be by Rise (y) over Run (x)

1/1 = 1

y = mx + b is our equation for lines.  M is the slope.  Now we solve for B, by plugging one of our points into the equation.

-1 = 1(4) + b

-1 = 4 + b

-5 = b

Now that we have B, we have our full equation.  y = x -5.  Hope this helped!

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
