Jakes mom went shopping for school supplies. She bought 5 packs of pencils for 2.99 each and 8 notebooks for n dollars each. She spent a total of $25.35. Write and solve an equation to find the cost of one notebook

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!
