You can move the

**BIG BLACK POINTS**anywhere you'd like.**Questions:**1) How can you calculate the length of the green segment, or

**|RISE|**, WITHOUT counting spaces (or gridlines)? 2) How can you calculate the length of the red segment, or

**|RUN|**, WITHOUT counting spaces (or gridlines)? 3) Let's call "

*" the distance between point*

**d***A*and point

*B*. Write an equation that expresses the relationship among

*,*

**d****|RISE|**, and

**|RUN|**. 4) Use the relationship you wrote for (3) to calculate the distance between

*A*(-3, 4) and

*B*(2, -6)

*without*using the applet above. After you arrive at your answer, use the applet to check your work.
