Answer:
H) -6/13
Step-by-step explanation:
To find the slope of the line between a pair of two points, use the slope formula, 
. Substitute the x and y values of (12,7) and (-14,19) into the formula and simplify like so:
So, Option H is correct.
Answer:
$38
Step-by-step explanation:
If there are three adults (or not-students) then that amounts to $30
(10*3)
Since they all go in one car they only pay $8
Add them all together!
The equation of the line that passes through the points
(1,5) and (5,13) is y=2x+3
There are 7 marbles, including 3 green ones, so at the start, there is a 3/7 chance of getting a green marble.
Assuming you did get a green one, there are now 6 marbles left, with 2 blue marbles, so there is a 2/6 chance of taking a blue marble.
Given that both have to happen, you must multiply each probability, hence the total probability is 3/7 x 2/6, or a 1/7 chance.
Hope this helped
