Answer:
Explanation:
Slope =∆y/∆x
M=(y2-y1)/(x2-x1)
Given points (5,-7) and (5,3)
y1=-7. y2 = 3
x1=5 and x2=5
M=(3--7)/(5-5)
M=10/0
M= infinity
This shows that the line is a vertical line parallel to the y axis.
That is at x= 5 y=3
And at x=5 y=-7
Therefore the graph is a vertical graph and has no slope it is 90° to the horizontal..
