Question

Find the slope of the line that contains the following pair of points. (1, 2), (5, 2)
A. -1
B. 0
C. 4
D. Undefined

Answer 1

i think it is c

Answer 2

Step 1) subtract the y coordinates of each point
Step 2) subtract the x coordinates in the same order
step 3) divide the differences (y over x). Reduce the fraction as much as possible

Answer 3

its 4

Answer 4

Step 1) subtract the y coordinates of each point
the y coordinates are 2 and 2, so 2-2 = 0


Step 2) subtract the x coordinates in the same order
the x coordinates are 1 and 5, so 5-1 = 4


step 3) divide the differences (y over x). Reduce the fraction as much as possible
(y difference)/(x difference) = 0/4 = 0


so the slope of this line is 0. This means we have a flat horizontal line
