Slope is the change in y-values divided by the change in x-values. You can use the following formula to calculate slope:
y₁ - y₂ / x₁ - x₂
The coordinates: (1, 7) and (10, 1)
y₁ = 7
y₂ = 1
x₁ = 1
x₂ = 10
7 - 1 / 1 - 10
6 / -9
-2 / 3
Answer:
The slope of the line that passes through the points (1, 7) and (10, 1) is -2/3.
