Question

What is the slope of a line that passes through the points (-2, 4) and (3, 4)?

Answer 1

`0`
A line with slope `0` represents a HORIZONTAL line. i.e. a line parallel to x axis.

Explanation:

Slope of a line passing thorough two points;
`(x_1, y_1) & (x_2, y_2)`
is given by :-
slope `= m = (y_2-y_1)/(x_2-x_1)`

`therefore` in this case,
`(x_1, y_1) = (-2, 4)`
`(x_2, y_2) = (3, 4)`

`therefore` slope
`= (y_2-y_1)/(x_2-x_1) = (4-4)/(3-(-2)) = 0/5 = 0`

Hence slope of the line is `0`.

A line with slope `0` represents a HORIZONTAL line. i.e. a line parallel to x axis.
