• Slope of UR
The formula used in finding the slope between two points is given by;

To find slope RS;
R (-3,9),S(-9,3)
x₁ = -3 y₁=9 x₂=-9 y₂=3
Substitute the values into the formula and simplify.

Hence, slope RS = 1
Slope ST
S(-9,3),T(-6,0)
x₁ = -9 y₁=3 x₂=-6 y₂=0
Substitute the values into the formula and simplify.

Hence, slope ST = -1
Slope TU
T(-6,0) , U (0,6)
x₁ = -6 y₁=0 x₂=0 y₂=6
Substitute the values into the formula and simplify.

Hence, slope TU = 1
Slope UR
U (0,6), R (-3,9)
x₁ = 0 y₁=6 x₂=-3 y₂=9
Substitute the values into the formula and simplify.

Hence, slope UR = -1
