Which relation is a direct variation that contains the – Question: Which relation is a direct variation that contains the ordered pair (2, 7)? Y=4x-1 y=2/7x y=7/2x y=7/xanswers ✅✅ Y=7x because that's the answer Which relation is a direct variation that contains the ordered pair (2, 7)? y = 4x – 1 y = startfraction 7 over x endfraction y = two-sevenths x y = seven-halves x – al…The relation or y = seven-halves x is direct variation. Step-by-step explanation: Given: The ordered pair = (2, 7). Now, to get the direct variation: As (2,7) lies on it. So, direct variation means. Now, Now, to get the direct variation: or y = seven-halves x. Therefore, the relation or y = seven-halves x is direct variation.

Which relation is a direct variation that contains the – What ordered pair does a direct variation always go through when graphed? answer choices (0, 0) (1, 0) (0, 1) (1, 1) Tags: Question 12 . SURVEY . 300 seconds . Q. Determine the type of variation: In a direct relationship the constant of variation is the product of x and y, and in an inverse relationship the constant of variation is theDirect Variation. When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation.. In simpler terms, that means if A is always twice as much as B, then they directly vary.If a gallon of milk costs $3, and I buy 1 gallon, the total cost is $3.Check It Out! Example 2a Tell whether the relationship is a direct variation. Explain. Method 2 Find for each ordered pair. This is not direct variation because is the not the same for all ordered pairs. 19. Tell whether the relationship is a direct variation. Explain. Check It Out! Example 2b Method 1 Write an equation. y = -4 x Each y-value

Which relation is a direct variation that contains the – The constant of variation for direct variationn* k is the coefficient of x. The variables y and x are said to vary directly with each other. ~{For y = kx, y is a function of x. If x = 0, then y = 0, so the graph of a **direct** **variation**, solve for y. If the equation can be written in the form y = kx, where k ≠ 0, it represents a **direct** **variation**}(2, 10), (8, 2), (7, 21), (2, -16) Direct Variation A direct variation is a mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to aDirect Variation (also known as Direct Proportion) The concept of direct variation is summarized by the equation below. We say that varies directly with if is expressed as the product of some constant number and . Cases of Direct Variation However, the value of can't equal zero, i.e. . Case 1: ( is positive) If increases then … Direct Variation Read More »
