Weby varies directly with x. If y = -18 when x = 9, find y when x = 7. y = kx-18 = k (9)-18/9 = k (9)/9-2 = k, constant of direct variation. To solve for y, use the constant of variation, -2 when x = …
WebSolution: Divide each value of y y by the corresponding value of x x. The quotient of y y and x x is always k = - \,0.25 k = −0.25. That means y y varies directly with x x. Here is the equation that represents its direct variation. Here is the graph. Having a negative value of k k implies that the line has a negative slope. WebQuestion: Id y=-11.7 when x=-3, find the value of y when x=7. Id y=-11.7 when x=-3, find the value of y when x=7. Expert Answer. Who are the experts?

WebJul 7, 2016 · 1 Answer Acquaintance Jul 7, 2016 y = 8 3 4 when x = 4 Explanation: An inverse variation: y = k x We are given y and x. We need to solve for k so we can find y when x equals 4. 5 = k 7 7 1 ⋅ 5 = k 7 ⋅ 7 1 35 = k We found what k is, so know we can make our inverse variation equation. y = 35 x Now let's plug in 4 for x to find y. y = 35 4 y = 8 3 4 Weby = 2×1 + 1 = 3 Check for yourself that x=1 and y=3 is actually on the line. Or we could choose another value for x, such as 7: y = 2×7 + 1 = 15 And so when x=7 you will have y=15 Positive or Negative Slope? Going from left-to-right, the cyclist has to P ush on a P ositive Slope: Example 2 m = −3 1 = −3 b = 0 This gives us: y = −3x + 0
WebApr 23, 2024 · Experienced Physics Teacher for Physics Tutoring. See tutors like this. Direct variation means the ratio of y to x is constant. y 1 /x 1 = y 2 /x 2 ⇒. y 2 = (x 2 /x 1) y 1. Plug in. x 1 = 3. y 1 = 7. x 2 = 7.
