Question

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

Answer 1

725

Explanation:

Hello!

You can substitute 23 for x in the equation y = 25x + 150, to find the predicted y-value.

Solve for y

• y = 25x + 150; x = 23
• y = 25(23) +150
• y = 575 + 150
• y = 725

The value of y at x = 23 is 725.

Answer 2

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
