Curt filled 120 cups with juice for the party. He placed 15 cups on each tray. He accidentally spilled 3 trays of juice. How many trays of juice does he still have for the party?

30 treys left I think

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!
