Response for: Question $6,$ Inline answer $4$ of $4$

Good job! Since the explanatory variable was also transformed, we need to indicate that in the equation.

Response for: Question $6,$ Inline answer $3$ of $4$

Well done! The slope is the value that follows the $+$ sign in the equation.

Response for: Question $6,$ Inline answer $2$ of $4$

Great job! The y$-$intercept is the value that immediately follows the equal sign in the equation.

Response for: Question $6,$ Inline answer $1$ of $4$

Awesome: The values of y were transformed, so we need to indicate that in the equation. We do so by using ln$($y$)$

in the equation instead of just y$$

Response for: Question $7,$ Inline answer $2$ of $2$

Great! The response variable is moisture content$(\%).$ The $^$ over the y indicates a predicted value.

Response for: Question $7,$ Inline answer $1$ of $2$

Outstanding! The explanatory variable is frying time in seconds.
