Complete the equation of the line through(−6,−5),(-4,-4)

y=ax+b

bring in (-6,-5)

=>-5=-6a+b

=>6a-5=b

bring in (-4,-4)

=>-4=-4a+b

=>4a-4=b

b=6a-5=4a-4

6a-5=4a-4

2a=1

a=1/2

then b=6*(1/2)-5=-2

y=ax+b

=>y=(1/2)x-2

ok

step-by-step explanation:

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
