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

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.

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
