Aline includes the points (10,1) and (a,-5) has a slope of 1/3. what is the value of a?

For this case we have that by definition, the slope of a line is given by:

Where:

are two points through which the line passes.

According to the statement we have:

Substituting we have:

Thus, the value of a is -8.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road

it is c!
