Apainter charges $35 per hour for labor plus $40 for a ladder rental when he paints a house. the customer provides the paint. the total charge to paint a customer's house was $950. how many hours did the painter spend painting this house?

26 hours because you subtract 40 from 950 since the painter needs 40 for a ladder then you get 910.then you divide(910÷35)...that's how you get 26

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!
