(a) Find an equation for the family of linear functions with slope 2. (Use the standard coordinate variables x and y. You may use m for the slope and b for the y-intercept as needed.) Sketch several members of the family. (b) Find an equation for the family of linear functions such that f(2) = 1. (Use the standard coordinate variables x and y. You may use in for the slope and b for the y-intercept as needed.) Sketch several members of the family. (c) What equation belongs to both families? (Use the standard coordinate variables x and y.)
