The slope of the line that passing through the given points is -9/7.
Given that the line that passes through the two points is (1,12) and (8,3).
We want to find the slope of the given line.
Here, we are given the x-coordinates with their corresponding y-coordinates.
We will use the formula here to find the slope between 2 coordinates of a line is
y₂-y₁=m(x₂-x₁)
The given points is (1,12) and (8,3).
Here, x₁=1, x₂=8, y₁=12 and y₂=3.
Now, we want to substitute the values in the above formula, we get
3-12=m(8-1)
Further, we will simplify the both sides, we get
-9=7m
Furthermore, divide both sides by 7, we get
-9/7=7m/7
-9/7=m
Hence, the slope of the line that passes through the given two points (1,12) and (8,3) is -9/7.
