WebIf the rate of change is constant, a graph of the measured quantity vs. time will be a straight line, and you can find the rate of change by calculating the slope of the line. WebJun 1, 2024 · Solution: We know that y y varies proportionally with x x. We can write the equation of the proportional relationship as y = kx y = k x. Substitute the given x x and y y values, and solve for k k. 40 = k(4) 40 = k ( 4) k = 40÷ 4 = 10 k = 40 ÷ 4 = 10. Therefore, the constant of proportionality is 10 10.

WebSummary: The type of variation can be identified by the graph of the relation. The graph of a direct variation is a straight line and starts at the origin. The slope of the line is the constant of variation. The equation of a direct variation is of the form y = mx, more commonly written as y = kx. 4. Practice:

WebIn your equation, "y = -4x/3 + 6", for x = 1, 2, and 3, you get y = 4 2/3, 3 1/3, and 2. For x = -1, -2, and -3, y is 7 1/3, 8 2/3, and 10. Notice that as x doubles and triples, y does not do … Webk = 25 4. So the constant of proportionality becomes: k = 6.25.
