What is the steepness of the line passing thru (1,2) and (3,8)

The slope of the line passing thru (1,2) and (3,8) is 3.

Step-by-step explanation:

The slope of a line measures its degree of steepness and is sometimes referred to as the gradient. The general formula for slope is; change in y/change in x. In this case; slope = (8-2)/(3-1) =3

3

Step-by-step explanation:

The steepness refers to the absolute value of the slope of the line.

Let and .

Then the slope is given by the formula;

We substitute the values to obtain;

The steepness is

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
