please show your work so I can know how to do this
Slope of a line between 2 points of a line given by Δy , =
difference in vertical coordinates of 2 points
ΔX difference in the horizontal coordinate of 2 points
X = 5 is a line parallel to Vertical axis:
All points along the line X=5 have the same vertical value , their difference is always f 0 ,
then:
ΔY = 0
ΔX
Y =8 : is a line parallel with horizontal axis : all points along it have the same value of X, therefore;
the difference is always 0
Δx = 0
Δy = Δy = undefined
Δx 0
