A line passes through point (8, -8) and has a slope of -3/2 . Write an equation in Ax+By=C form for this line. Use integers for
olchik [2.2K]

y = -3/2(x) + b

-8 = -3/2(8) + b

-8 = -12 + b

b = 4

y = -3/2(x) + 4

3/2x + y = 4

Hope this helps!! :)

Mrs. Eaton's class is participating in the "Box Tops for Education" campaign. On the first day, her
FrozenT [24]
The exponential model would take the form: 
y=Ae^{kt}&#10;
A, the initial value is 2, we will use 3 days and 8 tops to find k, or the rate.
8 = 2e^{k*3}
k =  \frac{ln(4)}{3}

Now, plugging in 6 days:
y = 2e^{ \frac{ln(4)}{3}*6}
y = 32

The linear would take the form:
y = mx+b
First the slope would be: (8-2)/(3-1) = 3
And to find b we could plug in the point (8,3):
8 = 3(3)+b
b = 8-9
b = -1
y = 3x-1
At x=6
y = 3(6)-1
y = 17

Thus, the exponential is almost double the result of the linear! Hope that helps.
