Straight line equation vs price-demand equation

JJames85005y ago
Hi Great lectures - thanks! Can you please quickly help explain the straight line demand equation and how it relates to p=a-bx? Q162 in bpp kit asks you to derive a straight line demand equation and solution presents you with price-demand equation. Im confused - thanks!

Ps I understand the straight line equation to be y=a+bx

P = a - bQ is a straight line because there are no powers of P or Q. So asking for the straight-line equation is simply asking for the equation P = a - bQ
