with what?
OpenStudy (anonymous):
Write a function rule for finding the amount of daily pay, p, in the following situation: A bus driver gets paid $100 each day plus $0.20 per kilometer, k. (1 point)
100 = 0.20 × k
p = 0.20 × 100 × k
p = 0.20k + 100
0.20k = 100 + p
i think its Yes, they show a linear function; y = 2x + 2.

The $100 paid is the fixed cost, this is the amount they pay no matter how many kilometers driven
so b = 100
The variable cost is $0.20, which means the slope is m = 0.20
So
y = mx + b
y = 0.20x + 100
p = 0.20k + 100
is your equation

thanks (((: can you help me with another one ?
jimthompson5910 (jim_thompson5910):
when talking about any cost equation in the form y = mx + b
the variable b is your fixed cost
the variable m is the variable cost
jimthompson5910 (jim_thompson5910):
sure

Write an equation for the line shown in the graph.
10 = 4x
y = 2x + 10
y = 10x – 2
y = –x + 10
