TALK the TALK Connecting Similar Triangles
and Slope of a Line
Audra was absent for this lesson on the connection between
similar triangles and the slope of a line. Write an explanation of
what you learned in this lesson. Be sure to include how you can
use a graph to determine the slope of a non-vertical line, and
how you can use similar triangles to show the slope is the same
between any two points on the line.

Finally, the arena decides to offer advertising space on the jerseys of the arena’s own amateur volley ball team. the arena wants the probability of being shortlisted to be 0.14. what is this as a percentage and a fraction? what is the probability of not being shortlisted? give your answer as a decimal. those shortlisted are entered into a final game of chance. there are six balls in a bag (2 blue balls, 2 green balls and 2 golden balls). to win, a company needs to take out two golden balls. the first ball is not replaced. what is the probability of any company winning advertising space on their volley ball team jerseys?
