1). the submarine is descending 100 feet per minute. this is because the line decreases 100 on the y axis when the x axis increases by 1.
2). the submarine is descending 50 feet per minute. this is because the line decreases 50 on the y axis when the x axis increases by 1.
3). y=15x this is because the slope increases by 15 on the y axis when 1 is increased on the x axis. the y intercept is 0. this means that every hour of piano lessons they get paid $15.

Answers

Answer:

.75

Step-by-step explanation:

You have to do B * H / 2   which 1.5 x 1 = 1.5, and then 1.5/2 = .75

In order to find the area of a triangle, you must do 1/2 base x height.

So to plug in the numbers, you will have 1/2 x 1 x 1.5.

1/2 x 1 = 0.5 and 0.5 x 1.5 = 0.75

A line passes through the point (2,-6) and has an initial value of 6. What is the rate of change for this line?
A. -12
B. -6
C. -1/6
D. 6

Answers

-6
Just did the question

-6

We assume "initial value" means the y-intercept is (0, 6). The rate of change is the "rise" divided by the "run" between the two points.

rise = -6 -6 = -12 . . . . difference of y-values

run = 2 -0 = 2 . . . . . . difference of corresponding x-values

rate of change = rise/run = -12/2 = -6

The rate of change of this line is -6.
