Ok. you're looking for the slope intercept, or how much each of them had before they started saving. Chris had $27, as that is where his line crossed the y axis, and Connie, when graphed, intercepted at $9. <span />
The answer is yes. The triangles are congruent.
I measured them with a ruler and they are the same length.
Hope this helped! c:
