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

telo118 [61]

Step-by-step explanation:

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

change in y axis ÷change in x axis

<h3> $slope = \frac{change \: in \: y}{change \: in \: x}$ </h3>

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

Suppose Johnny invests $41,745 into an account, which has been earning interest for many years and he now has a total of $39,974

Dmitriy789 [7]

Answer:

A negative number would be reasonable in the solution of the rate of the investment. It would be reasonable because Johnny started out with $41,745 in his account and ended up with $39,974 which means that the rate has to be negative.
