Consider the lines y=3x+5 2y=4x+5 3y=9x-2 2y=x-3 4y=x-5. Let's say that a pair of lines is good if the two lines are either parallel or perpendicular to each other. Among all the pairs of lines shown, how many pairs are good?

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
