in her free time, jackie likes to play an online math game. she noticed that, as she advanced to higher levels, her scores generally increased. jackie tracked her level, x, and score, y, over several weeks. then, she calculated a line of best fit. the equation for the line of best fit is y = 8.1x + 4.5. in this context, what does the slope of 8.1 tell you? jackie started the game with about 8 points. jackie played about 8 levels of her game. jackies score increased about 8 points per level. jackies score increased about a point every 8 levels.

Answer

Brief Explanations:

In the equation of a line $y = mx + b$ (where $m$ is the slope and $b$ is the y - intercept), the slope represents the rate of change of $y$ with respect to $x$. Here, $x$ is the level and $y$ is the score. So, for every 1 - unit increase in the level ($x$), the score ($y$) increases by the value of the slope.

Answer:

Jackie's score increased about 8 points per level.
