Write the equation of the line that passes through (2,3),(0,9)

y = -3x + 9

Step-by-step explanation:

The equation of a line is

y = mx + c

Step 1: find the slope

Two points given

( 2 , 3) ( 0 , 9)

m = y2 - y1 / x2 - x1

x1 = 2

y1 = 3

x2 = 0

y2 = 9

m = 9 - 3 / 0 - 2

m = 6/ -2

= -3

Step 2 : substitute any of the two points given into the equation of a line

y = mx + c

m = -3

y = -3x + c

( 2 , 3)

x = 2

y = 3

3 = -3(2) + c

3 = -6 + c

c = 3 + 6

c = 9

y = -3x + 9

The equation of the line is

y = -3x + 9

correct

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
