Answer :
The slope of the line passing through point (3, -3) and (18, -3) is equal to zero.
If we need to find the slope of line passing through any two points (x₁, y₁) and (x₂, y₂) then for this the formula is expressed as
m = (y₂ - y₁)/(x₂ - x₁)
where m is the slope and (y₂ - y₁) and (x₂ - x₁) are difference between y and x coordinates respectively.
We have the points (3, -3) and (18, -3) the slope will be
m = (-3 + 3)/(18 - 3)
m = 0
Now, we have the points (-3, 3) and (18, 26) so slope will be
m = (26 - 3)/(18 + 3)
m = 23/21
Now, we have the points (-2, -5) and (-3, -6) so the slope will be
m = (-6 + 5)/(-3 + 2)
m = 1
