Here we work in the system of integer polynomials. Those are polynomials of the Form f(x)=rnxn+···+r1x+r0 where every coefficient is an integer. General question: When does some combination of the polynomials ax + b and cx + d equal 1 ? That is, when do there exist integer polynomials P(x) and Q(x) with P(x)·(ax + b) + Q(x)·(cx + d) = 1 ? We concentrate here on cases when c = 0. (a) Prove: No combination of 2x + 5 and 3 can equal 1. That is, no integer polynomials P (x), Q(x) can satisfy: P (x)·2x + 5 + Q(x)·3 = 1. (b) Find a combination of 2x + 5 and 4 that equals 1. (c) Does some combination of 15x+9 and 25 equal 1? How about 15x+9 and 20? Explain your reasoning. (d) Investigate further examples of ax + b and d, deciding in each case whether 1 is a combination. What patterns do you detect? Can you prove that some of your observed patterns always hold true?

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?
