What is the slope of the line?
Coordinate grid showing both the x- and y-axes from -5 to 5 and a line graphed connecting the points left parenthesis negative 5 comma 4 right parenthesis and left parenthesis 5 comma 4 right parenthesis.
(1 point)
A) undefined
B) 0
C) –4
D) 4
The slope of a line can be determined using the formula
m = (y2 - y1) / (x2 - x1)
In this case, the coordinates of the two points are (-5, 4) and (5, 4). Plugging these values into the formula, we get
m = (4 - 4) / (5 - (-5))
= 0 / 10
= 0
Therefore, the slope of the line is 0.
The correct answer is B) 0.
