Line AB contains points A(4, 5) and B(9, 7). what is the slope of AB?

May 2, 2022 at 10:35 am #20711::Slope of line AB which contains points A(4, 5) and B(9, 7) is

**2/5**.**Solution**Slope represented by

**m**of a line given two points on the line (x_{1}, y_{1}), (x_{2}, y_{2}) is as following= (y

_{2 }– y_{1}) / (x_{2 }– x_{1})Given two points are A(4, 5) and B(9, 7)

So, we have x

_{1}= 4, x_{2}= 9, y_{1}= 5, y_{2}= 7Substituting in the above formula, we get

Slope(m) = (7-5)/(9-4) => 2/5

So, the slope of the line is 2/5
