Answer: This means that Alex answered 14 questions correctly
Step-by-step explanation:
Slope, which is the same as gradient, is equal to
change in y axis ÷change in x axis
<h3>

</h3>
Our coordinates are (-12,-12) and (9,-9)
In (-12,-12),let the first -12 be <em>x1</em><em> </em>and the second one be <em>y1</em>
Same goes for the (9,-9), let 9 be <em>X2</em><em> </em>and -9l be <em>y2</em>
<em>
</em>
<em>
</em>
<em>
</em>
<em>=</em>0.1428571429
= 0.1429
