I don't do good with slope intercept, but I can tell you that Fit n Trim would be $80m and Fit for Life would be $75+55m.
Answer:
Step-by-step explanation:

diameter of human hair is around 0.0025cm
in scientific notation it is: 2.5x10^-3
To arrange the slopes we need to take their absolute values.
1. U<span>ndefined slope means a vertical line, so it is going to be steepest.
2.|4/3| = 4/3
3.|-3/2| = 3/2
4. 0 means horizontal line.
</span>From flattest to steepest: 0, -3/2, 4/3, undefined.
