Pizzas cost $12 each, tax included. You decide to give the delivery driver a $6 tip. Find the cost for 3 pizzas.

Aye bruh i don’t know this but someone else who smarter than us will answer this

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!
