Question

Find the slope of a line containing points (-2,8) and (5,3).

Answer 1

slope of a line that passes through
`(x_1,y_1)` and
`(x_2,y_2)` is

`(y_1-y_2)/(x_1-x_2)`

given the points (-2,8) and (5,2)
the slope between them is
`(8-3)/(-2-5)=(5)/(-7)=(-5)/(7)`

the slope is
`(-5)/(7)`

Answer 2

(-2,8)(5,3)

slope = (y2 - y1) / (x2 - x1)
slope = (3 - 8) / (5 - (-2) = - 5/7 <==
