Answer:
b= - 3
Step-by-step explanation:
4(4b + 3) + 2b = 3(b - 11)
16b + 12 + 2b = 3b - 33
18b + 12 = 3b - 33
18b - 3b = -33 - 12
15b = - 45

b = -3
Every time we increas x by 1, we also increase y by 9. This means that the slope is 9:

When you know the slope
of a line and one of its points
, you can write the equation of the line using the formula

In your case, if for example we use the first point, we have

8 miles;
$20 - $1 (the tip) = $19
$19 - $3.00 = $16
$16 divided by the $2.00 per mile = 8 miles
I’m pretty sure that’s it, hope it helps!
