Answer:

28 miles in 7 minutes, 240 miles in an hour

Step-by-step explanation:

We can first simplify the rate to miles per minute. Since the plane goes 12 miles in 3 minutes, we can divide it by 3 to find how much it travels in one minute. 12 divided by 3 is 4 and 3 divided by 3 is 1

The plane travels 4 miles a minute

To find how much it travels in 7 minutes, multiply by 7

4x7 is 28

28 miles in 7 minutes

To find an hour, multiply by 60

4x60= 240

240 miles in an hour

Answer:

$y - 35 = 6(x - 5)$

Step-by-step explanation:

The point-slope equation of a line is

$y - y_1 = m(x - x_1)$ ,

where

$m = slope = \dfrac{y_2 - y_1}{x_2 - x_1}$

and the point is

$(x_1, y_1)$

Let's find the slope.

$m = slope = \dfrac{-31 - 35}{-6 - 5}$

$m = \dfrac{-66}{-11}$

$m = 6$

We are asked to use the first point in the equation, so

$x_1 = 5$ and $y_1 = 35$

The equation is:

$y - 35 = 6(x - 5)$
