Answer:
$103.6 left
Step-by-step explanation:
First, multiply the amount she earns an hour times how many hours she worked:
9.25 x 14 = 129.5
Then divide the total by 1/5:
129.5 / 5 = 25.9
Then subtract that value from the total:
129.5 - 25.9 = 103.6
$103.6 is your answer
Hope this helps!

Answer:
(0,8)
Step-by-step explanation:
First, we must arrange this equation into slope-intercept form, or  y=mx+b form. 
Equation: y-8=2x
Add 8 to both sides: y=2x+8
Now that the equation is in slope-intercept form, it is easy to find the y-intercept, as it  is just the b-value. 
In this case, the b-value is 8, so the y-intercept is (0,8).
