Find the slope of the line in the graph below
Andru [333]
Answer =-3 or -3/1

You can either do rise/run
Or you can find two points on the line and do (y2-y1)/(x2-x1)

Two points on the line are (-1,2) and (-3,-4)
X1=-1 Y1=2
X2=-3 Y2=-4

(y2-y1)/(x2-x1) = (-4-2)/(-3-(-1)) =(-6)/(-3+1)
=-6/-2 = -3

So slope =-3/1 or -3 (same thing)

PLZ HELP I BEG YOU ITS URGENT
harkovskaia [24]

Answer:

$638.25

Step-by-step explanation:

The interest is 5.5% yearly and it is simple interest.

Now, if we consider a deposit of $575 into the bank account that earned 5.5% simple interest each year, then after 2 and half years James will get interest only for 2 years as the 3rd year's interest will be added after the 3rd year.

Therefore, if no money was deposited into or withdrawn from the account, then after 2.5 years the sum will be  

575(1 + \frac{5.5 \times 2}{100}) = 638.25 dollars. (Answer)
