Write a linear function through the points (0,9) and (1,27)

y = 18x + 9

Explanation:

(0,9), (1,27)

slope:

equation:

y - y₁ = m ( x - x₁)

y - 9 = 18 ( x - 0 )

y = 18x + 9

y= x + 9

Step-by-step explanation:

(0,9) , (1,27)

(-)÷(-) = slope

=1    =0    =27    =9

(1-0)÷(27-9) = 1/18

m = slope = 1/18

y- = m (x- )

y-9= (x-0)

y-9 = x

y= x + 9

17.08

correct me if i am wrong.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
