Question

Y varies directly as to x. When x = 4 y = 5.2. Find x when y = -13

Answer 1

Use the direct variation equation:\[\frac{ y }{ x }=k\] where k = the constant

To solve for y or x, rewrite the equation: \[y=kx\] Hope this helps

Answer 2

There are two parts to the equation. First look at your first statement of values that tells you x = 4 and y = 5.2. Use the first equation to solve for the constant (k). Then, plug in the second statement of values and the constant (k) that you solved for. It's just a simple plug and chug problem.
