Answer:
$120
Step-by-step explanation:
The initial fee that was charged is the y-intercept of the equation that represents the situation given.
Using the slope-intercept equation, y = mx + b, find m and then find b, which is the initial fee.
Where, x = distance, y = price, m = slope, and b = y-intercept, which is the initial fee that was charged that we are looking for.
First, using two pairs, (105, 183) and (140, 204), find the slope (m):
m = ⅗
To find the y-intercept, b, substitute x = 105, y = 183, and m = ⅗ into .
Subtract 63 from each side
The initial fee of the company is $120.
