Rachael is on a hiking trip with her friends. after 3 hours of hiking and at 6 miles from their starting point, they decide to take a
one-hour break to eat lunch and take pictures.

after 4 more hours, they reach their campsite 16 miles away from their starting point.

which graph correctly models this situation?

it has changed from the width and the height.

step-by-step explanation:

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

step-by-step explanation:

the true ones are a b and d

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
