WILL GIVE BRAINLIEST! A ball rolling down an inclined plane travels, in successive seconds, k feet, 2.5k feet, 4k feet, etc… . Find the distance traveled by the ball in the ninth second.

Step-by-step explanation:

this is an arithmetic series

and to find out the 9th term

1 second       k feet

2 second2.5 feet

3 sec4 feet

4 sec5.5 feet

difference 1.5

5 sec7 feet

6 sec8.5

7 sec10 ft

8

9second 13 ft

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
