Answer:
whats the question about the tho?
Answer:
C. (8,1)
Step-by-step explanation:
To know how much costs each marker you have to divide the total amount Mark paid, by the total number of markers, then:
![\text{Cost per marker}=\frac{2.16}{12}=0.18](https://tex.z-dn.net/?f=%5Ctext%7BCost%20per%20marker%7D%3D%5Cfrac%7B2.16%7D%7B12%7D%3D0.18)
Thus, each marker costs $0.18
(3,4)(2,-1)
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (-1-4) / (2 - 3) = -5/-1 = 5
y = mx + b
slope(m) = 5
u can use either of ur points...(3,4)...x = 3 and y = 4
now we sub and find b, the y int
4 = 5(3) + b
4 = 15 + b
4 - 15 = b
- 11 = b
so ur equation is : y = 5x - 11 <===
