Answer: -7-4
Step-by-step explanation:
Yes, so the Y intercept of the linear regression line is 250 ( it is on the y-axis at point [0,250]. You can also see that for every 2x the number on the y axis decreases by 50. This means that the slope is -25. Now put what we know into the equation for a line - y=mx+b
y = -25x +250
You would have to multiply $24 by 8% and then subtract from the total.
So, 24 x .8 = 19.2
24-19.2 = 4.8
$4.80 sales tax.
If you want to solve for y that would mean y=3x but if you solve for x it’s x=y/3.
