An object in a simulation accelerates from a rest speed of 4 meters per second in 2 seconds. it then accelerates linearly for the next 3 seconds until it reaches 10 meters per second. the object remains at that speed (acceleration=0) for 3 seconds and then de-accelerates linearly until it comes to rest 2 seconds later. which graph demonstrates the speed of the object for those 10 seconds?

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
