Jenna has 30 batteries she is organizing her batteries into six boxes she puts the same number of batteries in each box write an with expression that you can use to find the number of barrettes in each box

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!
