find the slope using the slope formula of 1,2 and 7,9
The slope formula is given by:
m = (y₂ - y₁) / (x₂ - x₁)
Given the points (1,2) and (7,9), let's identify the coordinates as follows:
x₁ = 1, y₁ = 2
x₂ = 7, y₂ = 9
Now, let's substitute these values into the slope formula:
m = (9 - 2) / (7 - 1)
m = 7 / 6
Therefore, the slope of the line passing through the points (1,2) and (7,9) is 7/6.
