Question

What is the slope of (-12,-12) and (9,-9)

Answer 1

Step-by-step explanation:

Slope, which is the same as gradient, is equal to

change in y axis ÷change in x axis

$slope = \frac{change \: in \: y}{change \: in \: x}$

Our coordinates are (-12,-12) and (9,-9)

In (-12,-12),let the first -12 be x1 and the second one be y1

Same goes for the (9,-9), let 9 be X2 and -9l be y2

$slope = \frac{y2 - y1}{x2 - x1}$

$= - \frac{ - 9 - - 12}{9 - 12}$

$= \frac{3}{21}$

=0.1428571429

= 0.1429
