Question

How do you find the slope of the line passing through the points (–4, 3) and (10, 3)?

Answer 1

slope is zero.

Explanation:

Use the slope formula: `m=(y_2-y_1)/(x_2-x_1)`

`m=(3-3)/(10--4)=0/14=0`

A quicker way is to recognize that the y-coordinate is the same in each point. This means the line must be a horizontal line. All horizontal lines have a slope of 0.

Answer 2

slope m=0

Explanation:

we know the slope of a line passing through two points ( `x_1,y_1`) and ( `x_2,y_2`) is
m= `y_2-y_1//x_2-x_1`

so
m= `3-3//10-(-4)`
m=0/14
m=0

`tan(theta)`=0
