Awalkway rises 0.5 ft for every 5 ft. on the horizontal. find its slope

Slope = 0.1

Step-by-step explanation:

The slope measures "RISE" over "RUN".

The "rise" is the change happening in the y-direction (or vertical direction)

The "run" is the change happening in the x-direction (or horizontal direction)

We divide "rise" by "run" to get the value of slope.

Here, the rise (vertical) is 0.5 feet

Also, the run (horizontal) is 5 feet

Thus,

Slope = Rise/Run =

So,

Slope = 0.1

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
