Question

(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework? WILL MARK AS BRAINLIEST IF YOU SHOW WORK

Answer 1

Assuming that $x$ is the amount of hours spent doing homework:

Plug in $3$ for $x$

$y = 8(3)+40$, $y=64$

That means that since a $y$ value is the test score (because that's what the y-axis is labeled), your predicted test score is a 64.
