Salma made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $35.40. If the beads cost $2.60 for each necklace, how much did each pendant cost?

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!
