WebThe table is basically a representation of what y or x is equal to once you multiply it by the proportionality constant. if our equation was y=2x, if x is 1 we can say y=2*1 or y=2. if x is 2 then y=2*2 or y=4 and so on and so forth. I hope this helps :) x y. 1 2. 2 4. WebMay 11, 2015 · If the answer is yes the variables vary in direct proportion to one another, which we can write as y ∝ x If we denote this constant of proportionality by k, we have Multiplying both sides by x then gives y = kx This can be compared with the general equation of a straight line y = mx + c with gradient m = k and intercept c = 0.

Directly Proportional and Inversely Proportional

WebWhat this equation tells you is that for whatever value of x, y will equal 4 divided by that value. Here, x and y are variables, their value changes. This means that the y-value depends on the x-value. They need not be fixed : x and y can … WebThe statement ‘t is directly proportional to r’ can be written using the proportionality symbol: \ [t \propto r\] If \ (y = 2p\) then \ (y\) is proportional to \ (p\) and \ (y\) can be...
