Question

The function is y= 220.

The graph of this function is a slope. Find its slope. Then tell what the slope represents

Answer 1

it's slope is 0.

Explanation:

Here, the function is,

y = 220

clearly, it represents a straight line parallel to x -axis with y-intercept = 220

since the straight line is parallel to x-axis, it's slope is 0.

In another way, let (
`x_(1) , y_(1)`) and (
`x_(2) , y_(2)`) be two points on the straight line y = 220 so,
`y_(1) = y_(2) =220` and suppose that
`x_(1) \\eq x_(2)`

then, slope of the line y =220 is given by

m =
`(y_(1) - y_(2))/(x_(1) - x_(2))` =0
