Trey needs 4 1/3 of wood for a project the home improvement store sells wood he needs in 10 foot boards if he buys 2 board's how much if it would he not use

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!
