Question

Find the slope of the line through the given points:(2.5, 3) and (8, 3.5

Answer 1

The slope m of a line that passes though the points (a,b) and (c,d) is given by:

$m=\frac{\Delta y}{\Delta x}=\frac{d-b}{c-a}$

For the points (2.5,3) and (8, 3.5):

$m=\frac{3.5-3}{8-2.5}=\frac{0.5}{5.5}=\frac{5}{55}=\frac{1}{11}$

Therefore, the slope is equal to 1/11.
