Answer:
2.5 cm/year
Step-by-step explanation:
Just divide the total distance, 250 cm, by the years, 100, 250/100 = 2.5, the rate of the contintents drifting away is 2.5 cm per year, 2.5 cm/year
Answer:
$7
Step-by-step explanation:
just did 21 divided by three since it says she has saved one third of the $21.

Answer:
the equation of the line in slope-intercept form is: 
Step-by-step explanation:
First start by finding the slope of the segment that joins those two points using the general formula for the slope of the segments between two points
and
on the plane:

Then for our case, calling (-4, 6) =
and (-8, 10) =
, we have:

Now, knowing this, we can find the equation of the line by using the "point-slope" form of a line [of slope "m" and going through the point
that tells us:

We will be then using the found slope (-1) and for example one of the given points: (-4 , 6), thus:
