Question

Find the slope between points (2, 10) and (-5, 12)

Answer 1

Answer:  

The slope between the points (2, 10) and (-5, 12) is m= -0.28.

Solution:

Given points are P = (2, 10) Q=(-5,12).  We have to find the slope between these two points

The slope of the line passing through the two points $p = (x_{1} , y_{1})$ and $q = (x_{1} , y_{2})$ is given as

$\mathrm{m}=\frac{\mathrm{y}_{2}-\mathrm{y}_{1}}{\mathrm{x}_{2}-\mathrm{x}_{1}}$

From the given points we have $x_{1}=2, y_{1}=10, x_{2}=-5, y_{2}=12$

Plug the given values into the formula for the slope:

$\mathrm{m}=\frac{12-10}{-5-2}=\frac{2}{-7}=\frac{-2}{7}$

Hence we get "m" = $\frac{-2}{7} = 0.28$

Answer 2

2/-7 is the slope (12-10)/(-5-2) is 2/-7
