WebAll direct proportion graphs must start at the origin. For example, If y y is directly proportional to x x then the graph will be a straight line. If y y is directly proportional to a function of x x such as x^ {2} x2 or \sqrt {x} x then the graph will form a curve. For inverse proportion, as one variable increases the other variable decreases. WebApr 8, 2024 · When we see the words "y is directly proportional to x", we immediately think of the direct proportion formula y = kx , where k is a constant. We are given that y = 10 and x = 2, so we want to find the constant by plugging these values into the formula: y = kx . 10 = k * 2. k = 5. So, we now have the equation y = 5x.
