Question

[lovehopefaith98]

I have another algebra question:

If y varies directly with x and x increases by 2, is it possible to determine by how much y increases or decreases? Explain.

When I figured it out, I put yes, it does, but I got it wrong. Either my explanation was inaccurate or the answer is no, it doesn't.

Thanks!

\(\displaystyle y \ \infty \ = x\)

that means

y_o = kx_o

where

y_o = old y

x_o = old x and

'k' = proportionality constant but we do not know the numerical value of 'k'.

Now if you increase x_o by 2, then new y_n (new y) would be:

y_n = k (x_o+2) = kx_o + 2k

Since we do not know the numerical value of 'k', we cannot calculate the the numerical value of y_n.
