Answer:
m = 300
Step-by-step explanation:
![m/5 = 60](https://tex.z-dn.net/?f=m%2F5%20%3D%2060)
multiply both sides of the equation by 5
![m = 60 * 5 = 300](https://tex.z-dn.net/?f=m%20%3D%2060%20%2A%205%20%3D%20300)
First find the equation of y.
![y=mx+n=\frac{\Delta y}{\Delta x}x+n](https://tex.z-dn.net/?f=y%3Dmx%2Bn%3D%5Cfrac%7B%5CDelta%20y%7D%7B%5CDelta%20x%7Dx%2Bn)
Find the slope m.
.
Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.
.
The equation of a line y is:
.
The perpendicular line
is same like the normal line except its slope m becomes:
.
The equation of a perpendicular bisector is thus:
.
Hope this helps.
The function that best represents the data is y = 0.75x + 4.5. The slope in this case represents the increase in the amount she spends in $ due to the number of cards she makes. The intercept with the Y axis (4.5) means that she has an expense of 4.5 $ without having made any card yet.
