Scott earns $35,000 per year, and pays 28% tax. how much does he pay in tax per year?

You can write:
0.28×35,000=$9,800 per year

Ido not know i use to

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!
