Each cd at a music store is sold for $10 if n represents the number of cds sold, which equation could be used to find the total number of dollars, d, the store receives from CD sells

10n=d

Explanation:

Each CD is sold for $10

The music store has sold n amount of CDs

The total number of dollars d depends on how many CD’s were sold

The equation is 10n=d

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!
