The marginal cost (MC) curve intersects the average variable cost (AVC) curve at the minimum point of the AVC curve.
When the marginal cost is below the average total costs or the average variable costs,then the AC would be declining.When marginal cost is above the average cost then the average cost would be increasing.Therefore the marginal cost should intersect with the average cost at the lowest point in order to pull the average cost upwards.

A firm's short run supply curve
a perfectly competitive firms supply curve will be the portion of the marginal cost curve which lies above the average variable cost curve (AVC)..this will be due to the firms unwillingness to supply below the price in which they could cover their variable costs
Characteristics of Perfectly Competitive Market: Free entry / exit (no barriers to entry) Firms produce homogenous products There is perfect knowledge of the market Many Seller and Buyers Seller is a passive price taker Marginal Revenue Curve = Average Revenue = Price = Demand Curve for individual firm. The curve is constant Marginal Cost Curve intersects both Average Variable Cost and Average Total Cost curves at their minimum point Profit Maximisation output level is when MR = MC (find intersect point and draw line down to Q axis)

When average total cost curve is falling it is necessarily above the marginal cost curve. If the average total cost curve is rising, it is necessarily below the marginal cost curve.

A perfectly competitive firm's supply curve is that portion of its marginal cost curve that lies above the minimum of the average variable cost curve.
Marginal cost curve cuts average cost (variable or total cost) at its minimum simply to portray the law of variable proportions. The idea is as labor is increased with capital being fixed, productivity increases upto a point and then decreases and later becomes negative. To relate the same productivity with average cost function, the average cost first decreases , reaches a minimum and then increases. Now marginal cost is just a change in the total cost. Logic says that when MC is less than AC productivity is favourable, thus cost is falling. When MC is more than AC productivity is not favourable and thus the rising portion of the cost curve. When MC = AC , the productivity that was reducing the average cost per unit has maximized and from then on starts rising cost(or decreasing productivity). That is the only point where they can intersect.
A perfectly competitive firm's supply curve is that portion of its' marginal cost curve that lies above the minimum of the average variable cost curve. A perfectly competitive firm maximizes profit by producing the quantity of output that equates price and marginal cost. As such, the firm moves along it's marginal cost curve in response to alternative prices. Because the marginal cost curve is positively sloped due to the law of diminishing marginal returns, the firm's supply curve is also positively sloped.
Marginal cost curve above the average variable cost curve, is the same as the short run supply curve. In perfect competition, MC=Price. It follows that production will be at that point. Hence the supply curve is the same as that part of the MC curve which is above AVC, where the firm can cover its variable cost....this is better than shutting down.
Marginal Cost will keep increasing (have upward slope) because of the principle of diminishing marginal returns. The MC curve above the its intersection with AVC is the Supply Curve *because below minimum AVC, the firms stops production)
