Adam calculates his annual salary (base pay and commission), y, using the model y=0.28x+38,000 , where x represents his total sales for the year.

Question

What is the y intercept?

Answer 1

In the equation \( y = 0.28x + 38,000 \), the y-intercept is the value of \( y \) when \( x = 0 \).

To find the y-intercept, we can substitute \( x = 0 \) into the equation:

\[ y = 0.28(0) + 38,000 = 38,000 \]

Therefore, the y-intercept is \( 38,000 \). This means that if Adam has no sales (i.e., \( x = 0 \)), his annual salary would be \( 38,000 \).
