From the problem we know that Hanna saves one-half of her paycheck each week, so she saves
![( \frac{1}{2})(160)= \frac{160}{2} =80](https://tex.z-dn.net/?f=%28%20%5Cfrac%7B1%7D%7B2%7D%29%28160%29%3D%20%5Cfrac%7B160%7D%7B2%7D%20%3D80)
. Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is
![80+50=130](https://tex.z-dn.net/?f=80%2B50%3D130)
.
Since we know that Hanna currently has <span>$1,280 in her saving's account and each week she and her parents deposit $130 to the account, with </span>
![n](https://tex.z-dn.net/?f=n)
representing the number of weeks, we can model the situation as follows:
Answer:
0.5+8
Step-by-step explanation:
The slope intercept form is mx+b
Mx is the slope
b is the y intercept
The slope formula is y2-y1/x2-x1
2 points to find the slope:
(2,9) (4,10)
10-9=1
4-2=2
1/2=0.5
The y-intercept is the number that goes through the number line when x equals 0. The y intercept is 8.
Answer:
-3
Step-by-step explanation:
complete operations and rearrange to y = mx + b format
y + 1 = -3(x-5)
y + 1 = -3x + 15
y = -3x + 14
slope is -3
