54. Suppose that a tennis tournament has 64 players. In how many ways can the 64 players be paired to play in the first round? Assume that each player can play any other player without regard to seeding.​

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
