A classic car increases in value from $5000 to $20000 over a period of 30 years

Use the formula r=(f/p)^1/n - 1

add an image, and i will answer

step-by-step explanation:

i can't solve unless i know what the line is

step-by-step explanation:

welcome to/p>

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
