Robbie makes $9.25 an hour working at the local shoe store. his paycheck shows that he worked 38.5 hours over the past week. how much money did robbie make? (not rounded to the nearest cent)

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!
