WILL MARK BRAINLIEST! What is the formula to calculate the slope? Is it y^2-y^1/x^2-x^1? Please type it in for me.

You are correct. Remember: rise over run.

m =

Step-by-step explanation:

the 2 and 1 represent which number they are in a series of points. For example, if I were to have points (1,2) and (3,4)

4 would be meaning it is the second y value

2 would be meaning it's the first y value

Same goes for x

3 is

1 is

so the equation for slope is , or 1

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
