OK. So first, slope = rise/run. This can be calculated with any 2 points from the graph above.
I will use points (24, 168) and (8, 56).
Slope = (168 - 56) / (24 - 8)
Slope = 7
Since the y-intercept is 0, the equation is y = 7x
B should be the correct answer.
Cheers,

Answer:
a = 15/2
Step-by-step explanation:
3a−15=4a−3a
Combine like terms
3a - 15 = a
Subtract 3a from each side
3a-3a−15=a−3a
-15 = -2a
Divide each side by -2
-15/-2 = -2a/-2
15/2 =a

Answer:
![80x\geq 750](https://tex.z-dn.net/?f=80x%5Cgeq%20750)
She'll need to save at least 10 months to be able to go buy the computer.
Step-by-step explanation:
Let
x ----> the number of months
we know that
The inequality that represent this situation is equal to
![80x\geq 750](https://tex.z-dn.net/?f=80x%5Cgeq%20750)
solve for x
![x\geq 750/80](https://tex.z-dn.net/?f=x%5Cgeq%20750%2F80)
![x\geq 9.4\ months](https://tex.z-dn.net/?f=x%5Cgeq%209.4%5C%20months)
therefore
The minimum number of months is 10
