What is not a description of slope?

Gelneren [198K]

Answer:

Option (d) is wrong.

Step-by-step explanation:

Slope is:

rise over run
The rate of change of a line
Change in y over the change in x
The ratio of vertical change to the horizontal change.

It can be given by mathematically as follows :

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{and}\\\\m=\dfrac{dy}{dx}$

Hence, the option which is not a description of slope is (d) "the ratio of horizontal change compared to vertical change"

a carpet layer can put down 400 square feet of carpeting in 2.5 hours. How many hours will it take him to lay 600 square feet of

N76 [4]

You can set it up like:

400/2.5 = 600/x; now cross multiply
400x = 2.5(600)
400x = 1,500; now divide both sides by 400 to isolate the x, and you get x = 3.75 hours
