Question

Find the slope of the line that passes through the points (2, 1) and (-1,-1).

Answer 1

slope is ⅔

Explanation:

`slope = (y_(2) - y_(1))/(x _(2) - x_(1) ) \\ \\ = ( - 1 - 1)/( - 1 - 2) \\ \\ = ( - 2)/( - 3) \\ \\ = (2)/(3)`

Answer 2

2/3

Explanation:

We can us the slope formula

m = ( y2-y1)/(x2-x1)

= (-1 -1)/(-1 -2)

= -2 / -3

= 2/3
