Deal with the numbers and variables step by step
-20/48 = -5/12
t5 / t7 = t^-2 = 1 /t2
u^2 / u^4 = u^-2 = 1/u^2
v^3 / v = v^2
so answer is -5v^2 / 12t^2u^2
The direct variation equation is y = kx.
In this case, the equation is y = 1.8x.
Substitute the given points into the equation. If the x and y coordinate of a point satisfies the equation and both sides are equal, then that point is your answer.
