A coordinate plane with a line passing through (negative 3, 2) and (0, 3)

Arturiano [62]

Let's check

$\\ \sf\longmapsto Slope=m=\dfrac{3-2}{0+3}=\dfrac{1}{3}$

Y intercept is 3✓

Now

let f(x) be y

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto y=\dfrac{1}{3}x+3=f(x)\checkmark$

Giving medal. A new car that sells for $21,000 depreciates (decreases in value) 16% each year. Write a function that models the

Natali5045456 [20]

$21,000-16%
16% of $21,000 is $3,360
$21,000-$3,360=$17,640
1st year would be $17,640

16% of $17,640 is $2,822
$17,640-$2,822 is $14,817
2nd year would be $14,817

16% of $14,817 is $2,370
$14,817-$2,370=$12,446
3rd year would be $12,446

$12,446 rounded would be $12,447

So A) $12,447

Hope this helps out :)
