Approximate the solution to this system of equations. (6 points)
y = βx + 3
y = 2x + 1
The first step is to identify y-values for different values of x. The table shows y-values for the two functions between x = -1 and x = 2.

y = βx + 3
y = 2x + 1

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
