i) Gradient (m) = ∆y/∆x. Therefore: m = (5-(-7))/(3-6) = (12)/(-3) = -4. Intercept (c) = 5-(3*(-4)) = 5+12 = 17. Therefore: y = -4x+17 ii) x = -2, y = 26. -4(-2) + 17 = 25. 25≠26, therefore the line does ...

Starting with the curves themselves, we have a downward sloping demand curve as more people are willing to buy at lower prices. Conversely, seller will be willing to offer more goods for sale as the price...
