Question

Using the trend line equation:Y=25X+150Using the trend line equation what is the value of y when x is 15

Answer 1

Given:

`y=25x+150`

Substitute x=15 in the above expression, then solve for the value of 'y'.

`\begin{gathered} y=25*15+150 \\ y=375+150 \\ y=525 \end{gathered}`

Thus, the value of y is 525 when x=15.
