Answer 1

a. The object is moving away from the starting point.

Answer 2

Correct. How about part B?

Answer 3

50-11=39

Answer 4

how are you getting those values?

Answer 5

what's the formula?

Answer 6

you use the slope formula

\[\Large m = \frac{y_2 - y_1}{x_2 - x_1}\]

Answer 7

how are you getting (0,11) ?

Answer 8

it looks more like (0,15)

Answer 9

Hmm, your right.

Answer 10

b. 10

Answer 11

@jim_thompson5910

Answer 12

10 seconds

Answer 13

10 is correct, but the units aren't "seconds"

Answer 14

then it's meters

Answer 15

keep in mind that slope = rise/run = distance/time = speed

Answer 16

so the units are meters/second = meters per second

Answer 17

How would I set up the equation for 'c' ?

Answer 18

the slope is m = 10
the y intercept is b = 15

y = mx+b is the general linear equation

Answer 19

y=10x+15

Answer 20

correct

Answer 21

x = time in seconds
y = position

Answer 22

for part d, plug in x = 10

Answer 23

115

Answer 24

yes
