Sagot :
The slopes of the given 4 sets of points are -11/8, -2, 6, and 2/5
we know that the slope of a line is calculated by
(y₂ - y₁) / (x₂ - x₁)
where x₁, x₂, y₁, and y₂ are any 2 given coordinates of a line.
The first set of points are (-7, 8) and (0,4)
Hence slope will be
(4 + 7)/(0-8)
-11/8
It is given that the points are (-1, -7) and (-2, -5)
Hence the slope will be
(-5 + 7)/(-2 + 1)
= 2/-1
= -2
We are also given points (5,4) and (7,10). Hence slope will be
(10 - 4) / (5 - 4)
= 6
The other set points are
(8,7) and (3,5)
Their slope will be
(7 - 5) / (8 - 3)
= 2/5
Hence the slopes are -11/8, -2, 6 and 2/5
