Question

amara always charges the battery of her motorized wheelchair overnight. at the end of each day, she records the distance she traveled and the remaining charge on the battery. the scatter plot shows the data.the equation of the line of fit is $y = -3.8x + 100$.amara rides 18 miles. use the equation to predict the remaining battery charge, $y$, when $x$ is 18.%

Explanation:

Step1: Substitute x=18 into equation

$y = -3.8(18) + 100$

Step2: Calculate the product term

$-3.8 \times 18 = -68.4$

Step3: Compute final y value

$y = -68.4 + 100$

Answer:

31.6 %
