Question

Find the slope of the line passing through (11, -2) and (2, -2).
A. 4/9
B. 9
C. 0
D. Undefined

Answer 1

Two generic points that define a straight line are (x1, y1) and (x2, y2)

In this case, (x1, y1) = (11, -2), which means x1=11 and y1= -2

and (x2, y2) = (2, -2), which means x2=2 and y2= -2


So x1=11, y1= -2, x2=2, and y2= -2.


-------------------



Now use the slope formula



m = (y2-y1)/(x2-x1)



m = ( -2-( -2))/(2-11)



m = ( -2+2)/(2-11)



m = 0/(-9)



m = 0



So the slope of the line that passes through the two points is 0
