Question

Predict using the equation of the trend line y=25X+150 what will the y value be when x =23?

Answer 1

Given the equation of the line :

$y=25X+150$

We need to find the value of y when x = 23

So, substitute with x = 23 at the given equation

$\begin{gathered} y=25\cdot23+150 \\ y=575+150 \\ \\ y=725 \end{gathered}$

So, the answer is : y = 725
