Answer:

The rise is -5 the run is 4

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

=

-5

4

=

-1.25

θ =  

arctan(

ΔY

) + 360°

ΔX

=

308.65980825409°

ΔX = 2 – -2 = 4

ΔY = -1 – 4 = -5

Distance (d) = √ΔX2 + ΔY2 = √41 = 6.4031242374328

Equation of the line:

y = -1.25x + 1.5

or

y =  

-

5

x

4

+  

3

2

When x=0, y = 1.5

When y=0, x = 1.2

Ashley took $20 out on her savings account each week on Friday. How many weeks ago did she have at least $250 in her account
tatuchka [14]
If she took $20 out of her savings account, given the information, she could easily have no money remaining now. Given this, we'll assume the current value of her account is the minimum it can be. Now you just need to find how many times her withdrawal can factor into the original amount, $250. Therefore, t=250/20= 12.5. Since it's asking for a number of weeks, the answer can't be a decimal, so your final answer is 12 weeks.
