Question

Find the slope of the line satisfying the following conditions.horizontal, through (6,5)

Answer 1

The slope of an horizontal line is always zero, it does not matter which point it passes thorugh.

This comes from the fact that in an horizontal line the y values of the points will always be the same, then from the definiton of the slope:

`m=(y_2-y_1)/(x_2-x_1)`

we notice that the numerator will be zero.

Therefore the slope is zero, that is:

`m=0`
